The best semiconductor among them all

Researchers have discovered a material that performs better than Silicon. Next, it will be possible to create it economically and practically.

Silicon is one of the most abundant elements on Earth. It has been the basis of many modern technologies, including solar cells and computer chips. However, Silicon’s characteristics as a semiconductor are not ideal.

One thing is that Silicon allows electrons to move through its structure quickly, but it is less friendly to “holes”, electrons’ positively charged counterparts. This is why some types of chips need to harness both. Additionally, Silicon is poor at conducting heat. This is why it is common to have overheating problems and costly cooling systems in computers.

MIT and the University of Houston researchers have demonstrated that cubic boron arsenide can overcome both limitations. It is extremely thermally conductive and has high mobility for electrons and holes. Researchers claim it is the best and most advanced semiconductor material.

Cubic boron arsenide was only made and tested in small batches. To test the small areas of the material, the researchers used special methods that Bai Song, an ex-MIT postdoc, had developed. It will take more research to find out if cubic boron arsenide is feasible in an economically viable form. This could be a major development over the current Silicon. Researchers say that the material’s unique properties could be used in some applications in the future.

Today’s findings were published in Science by Jungwoo Shin, MIT professor of mechanical Engineering, Gang Chen, Zhifeng Ren at MIT, and 14 other researchers at MIT, Houston, Texas at Austin, and Boston College.

Previous research, including that of David Broido (co-author of this paper), had predicted that the material would exhibit high thermal conductivity. However, experimental evidence has confirmed that prediction. Chen says that this latest analysis confirmed Chen’s prediction in 2018. He predicted that cubic boron arsenide would have high mobility for electrons and holes.

Previous experiments have shown that cubic boron arsenide’s thermal conductivity is nearly ten times higher than Silicon’s. Chen states, “So that’s very attractive for heat dissipation.” The material also had a good bandgap which gives it great potential to be used as a semiconductor material.

The new work now completes the picture. It shows that boron arsenide has all the essential qualities for a perfect semiconductor due to its high mobility for electrons and holes. This is important as semiconductors have both negative and positive charges. Chen states that if you build a device, it is important to use a material where electrons and holes can travel more easily.

While Silicon has good electron mobility, it is not as good for hole mobility. Other materials like gallium arsenide are used in lasers and have similar electron mobility.

Shin, the paper’s principal author, stated that heat is now a major bottleneck in many electronics. “Silicon carbide has been replacing Silicon in power electronics in the major EV industry, including Tesla. It has three times the thermal conductivity of Silicon despite having lower electrical mobilities. Imagine the potential of boron arsenides, which have a 10x higher thermal conductivity than Silicon and much greater mobility. It is a game-changer.

Shin says, “The crucial milestone that makes this discovery possible advances in ultrafast laser grating system at MIT,” originally developed by Song. He says that without this technique, it wouldn’t have been possible to show the material’s high mobility in electrons and holes.

He says that the electronic properties of cubic boron arsenide were first predicted based upon calculations of quantum mechanical density functions made by Chen’s team. These predictions were then confirmed by experiments at MIT using optical detection methods on samples taken by Ren and other University of Houston team members.

Researchers claim that the material has the highest thermal conductivity of any semiconductor. It also has the third best thermal conductivity of any material after diamond and isotopically enhanced cubic boron nitride. Chen said, “And now we predicted the electron-hole quantum mechanical behavior, starting from first principles and proved true.”

He says, “This is amazing because I don’t know any other material that has these properties, except graphene.” These properties are also found in bulk materials like this one.

He says the challenge is finding practical methods to produce this material in large quantities. It isn’t easy to make uniform material using current methods. The team needed to find ways to test small patches of material to get reliable data. Chen said that while they had demonstrated the material’s potential, it is not yet known if or where it will be used.

Chen says that Silicon is the industry’s workhorse. So, okay, we have better material, but will it offset the industry?” “We don’t know.” The material seems almost ideal for semiconductors, but “whether it can go into a device to replace some of our current markets, I think that has yet to be proved.”

Chen states that while electrical and thermal properties have been demonstrated to be excellent, many other properties, such as long-term stability, have yet to be determined. There are many factors involved in making devices. We don’t yet know them all.

He says that this could be a very important material and that people should pay more attention to it.

Ren states that commercial applications would require a grand challenge to make cubic boron arsenide. It took silicon decades to win the crown. Today, Silicon has a purity of more than 99.999999999%.

Chen states that the product must be commercially viable.

The cloud has permanently transformed infrastructure companies’ landscape – only ask IBM, HPE, CSC, and Atos

IT industry DXC Technology has hired consultants to help the elderly administration study a takeover bid.

During the time, DXC printed the provide, considered to be in the location of $10 million, as “inferior and missing certainty in light of the worth the board feels DXC can produce on a standalone basis by executing our transformation journey.”

DXC was forged in the shoot of a merger between two striving corporations, CSC and HPE Enterprise Services, and they came together in 2017 to improve economies of scale in a part of the technology market which was being decimated by the cloud as enterprises needed another consider the way they digest technology.

The strategy taken by the first administration group at DXC was to cut fees quicker than profits went off; this involved property consolidation, including data center place, and unrelenting redundancy times for the team on the infrastructure companies’ side. Morale internally slumped among some employees.

Dell XPS 15 (2020) review: new design, familiar problems

Dell XPS 15 (2020) review: new design, familiar problems

New look with everyday highs, expected lows

The Dell XPS 15 has finally received a fresh look after years of using the same stale, heavy chassis. The redesign is similar to that of the XPS 13 earlier this year. However, the same caveats apply. Although Dell’s changes to the machine may not seem significant, they make it feel like an upgrade.

Advertisement

The XPS 15 base model starts at $1299 and comes with a Core i5-10300H processor, 8GB RAM, a 256GB SSD, and Intel UHD graphics. This model is great for browsing, but the i7 will be your best choice if you require any computing power.

Currently, the XPS can be maxed out with a Core i7-1075H, 64GB RAM, and a 3840 x 2240 touchscreen. A 2TB SSD is available for $2,988. Although Dell claims there will be an i9 option in the future, I doubt they would recommend them to most customers. They will be more expensive, and I find it difficult to believe that a thin product can use such a powerful processor without burning itself.

Dell XPS 15 (2020) review: new design, familiar problems

THE GOOD

  • Excellent 16:10 display
  • Design upgrade: Upgraded bezel-free chassis
  • Excellent keyboard and touchpad
  • Full-size SD Card Reader

THE BAD

  • Battery life is below average
  • Loud fans with loads
  • Hot runs

A midrange model priced at $2,253 was tested for performance issues and bloatware. It comes with a Core i7-1075H, 16GB RAM (DDR4), a touchscreen, and a 512GB SSD. This configuration is suitable for most people. However, you need to know what storage you require. If you have 512GB of space, you might be able to fill it quickly with $100 more.

The most apparent changes are the bezels. The new XPS is equipped with the latest Dell Infinity Edge four-sided display. It has skinny bezels. It seems to stretch from one end to the other. It feels almost like you are looking at an OLED TV. The new laptop’s screen is 5 percent larger than its predecessor’s and has a 92.9 percent screen-to-body ratio.

Last year’s XPS 15 had a thick bottom bezel with a large Dell logo. That’s gone. It’s gone. It gives you a premium look (I got significant 2015 Inspiron vibes when I used the old bezel) and more screens to work with.

The XPS 15’s 16:10 aspect ratio is another excellent addition. Corning Gorilla Glass 6 is used to make the touchscreen. It has a 3840 x 2400, one of the highest resolutions on a consumer laptop. It’s far superior to 16:9. It was easy to use several windows and apps without zooming in or out. I could also stack hundreds of Edge and Chrome tabs without feeling cramped.

The new XPS 15 weighs in at 4.5 pounds, 13.6 x 9.1 x 0.7 inches, and is slightly lighter than last year’s model. It is 5.5 percent smaller. It is also slightly smaller (but heavier than the 16-inch MacBook Pro at 4.3 pounds, 9.8 x 0.88 inches) and smaller than the Razer Blade 15, which weighs in at 14 x 9.3×0.8 inches.

Dell also installed speaker grilles on both sides of the keyboard. There are two tweeters at the base. Waves MaxxAudio Pro is preinstalled on the XPS. This driver allows you to enable 3D audio or toggle between presets. The 3D feature made music sound great.

Accept to Continue: Dell XPS 15, 2020

Dell XPS 15 (2020) review: new design, familiar problems

Each intelligent device requires that you agree to specific terms and conditions before it can be used. These are contracts that nobody reads. We are unable to review and analyze all of these agreements. We counted how many times we had to click “agree” to use the devices. These are agreements that most people don’t read and can’t negotiate.

You must agree to these conditions before you can use the Dell XPS 15:

  • Request for your region
  • Request for your keyboard layout
  • Windows 10 License Agreement
  • Microsoft account
  • PIN
  • Support and Protection from Dell

You can also answer the following questions yes or no:

  • Wi-Fi
  • Windows Hello Face and Fingerprint Recognition
  • Activity history
  • Syncing Android phones
  • OneDrive Backup
  • Office 365
  • Cortana
  • Privacy settings (speech Recognition, location, Find My Device sharing diagnostic data, typing, inking, and tailored experience, Advertising ID)
  • McAfee security subscription

Dell XPS 15 (2020) review: new design, familiar problems

Final tally:

There are six mandatory and nine optional agreements for the XPS 15 keyboards and touchpads. They have been my favorite peripherals on my laptops, and Dell has improved both. The glass touchpad’s size (5.9×3.5 inches) has increased by 62 percent. It is as easy and smooth to click as ever. The keycaps are 9.75% larger than last year’s, which is a noticeable improvement. Keys have 1.3mm travel and are quick. I could maintain a pace of over 140 words per hour with very high accuracy. This is much more than what I have achieved on my most recent laptop.

A few keys have changed: the left and right Arrows are more significant than last year’s model. They extend to the bottom Shift keys. The power button, which includes a fingerprint reader, is now located in the top-right corner. The infrared camera supports Windows Hello facial recognition if you don’t wish to use the fingerprint scanner.

The USB-A, HDMI, and power ports have been removed from the previous model. This new model has three USB-C, two of which are Thunderbolt 3 and can be charged with any of them), a full-sized SD-card reader, an audio jack, and a wedge lock slot. The XPS 15 now has connectivity levels comparable to the MacBook Pro, although the card reader is a bonus feature you won’t see daily. The XPS 15 ships with a USB C to USB A dongle to support older peripherals.

 Review of Dell XPS 15 2020 specifications

  • Processor: Intel Core i7-1075H
  • RAM: 16GB
  • Storage: 512GB PCIe 3 x4 SSD
  • Graphics: Nvidia GeForce 1650 Ti 4GB DDR6
  • Display: 15.6 inch touchscreen (3840×2400).
  • Ports: Two USB-C Thunderbolt 3 ports, one USB-C 3.0, one SD Card Reader v6.0, and one 3.5mm Audio Jack. One wedge-shaped lock slot.
  • Cameras: 720p
  • Weight: 4.5 pounds (2.05kg)
  • Dimensions: 13.57×9.06x 0.71 inches
  • Windows 10 Home operating system

This XPS 15’s main selling point is its redesign, but the processor and graphics card inside has been upgraded. The eight-core 10th Gen processor could multitask and have a healthy amount of RAM. I could run around 12 Chrome tabs, Spotify, YouTube videos, and some downloads in the background without any problems.

However, the Nvidia GTX 1650 Ti graphics card is mid-range. It is not the best gaming option unless you are willing to sacrifice some visuals. If you are looking for a 15-inch gaming system, there are better choices from MSI, Alienware, and Razer at or below this price — and if your heart desires a 14-inch, the excellent Asus ROG Zephyrus G14 is an option. The 1650 Ti is capable of assisting with creative work as well as other tasks that require high productivity.

The XPS 15 took four minutes to export a 33-second, five-minute video in Adobe Premiere Pro. This is comparable to the results from the Surface Book 3 (15-inch) with a 1660 Ti MaxQ and a quad-core Core i7-1065G7, and much faster than the 16-inch MacBook Pro (16-inch) with a Core i9-9990HK and Radeon Pro5500M graphics. It was slower than Gigabyte’s Aero 15 creator-focused Aero 15 with the identical i7-1075H and an RTX2070 Super Max Q, which completed the same task in two minutes and 42 seconds. Fortunately, while the XPS 15’s exterior has been improved, the problems with cooling and power consumption of the older model have not changed. When I multitask, the dual fans of my laptop can often be heard in my room. Premiere Pro was also affected by them. While the touchpad and palm rests were extraordinary, the keyboard and undercarriage got hot when the laptop was being used under load. Dell is still unable to cool the chips in such a thin chassis.

Advertisement

My first battery test was with the XPS 15 being my primary work vehicle. I used the Better Battery profile and the screen at 200 nits brightness. However, I only got between 2:30 to 3:30 of my required juice. I could troubleshoot the results with Dell and found the issue was McAfee, a 30-day trial that comes preinstalled on my system. After uninstalling McAfee, I saw results in five hours and 45 mins. The moral of the story is to uninstall McAfee. This raises the question of why Dell has crapware on its $2,000 laptop.

A system with an H series processor, discrete GPU, and high-resolution display can deliver six hours of battery life. It’s still a disappointing result when compared with some of the competitors. Tom Warren, my colleague, got seven hours from Microsoft’s Surface Book 3 15-inch with similar apps and browser loads. The 16-inch MacBook Pro can last around eight hours. The XPS did not perform as well as the Gigabyte Aero 15 with a faster GPU and OLED screen. I managed to get five hours and 22 mins out of the Aero 15 workstation using the same method.

(Chrome, however, is a very power-intensive app. However, switching to Microsoft Edge did not improve the situation. Although I was able to get eight hours from a standard 1080p video rundown, I doubt many people will buy a $2,300 laptop to loop movies.

The Dell XPS 15’s battery life, fans, and cooling are good points. These aren’t new problems for the Dell XPS 15. It’s disappointing that Dell hasn’t yet found a better thermal design or way to cool a faster GPU. Even for such a powerful machine, the battery life is not great.

The XPS line has always been famous due to its excellent keyboard and touchpad, premium build quality, and stunning screen. The XPS’s modern design features, such as the bezel-less display, wider keycaps, slim form factor, and expanded speakers, give it a chic, contemporary look and better user experience. This model is a perfect choice if you have wanted to purchase an XPS 15 but was waiting for Dell’s outdated design to be scrapped.

The best digital whiteboards: Which one should I buy? And seven recommended school use models, such as Lidl's or productivity.

In classrooms, traditional chalk is mixed with pointers that let you erase quickly without leaving behind dust. There are screens where you can also launch content from your computer. The convenience, versatility, and variety of electronic digital whiteboards have made them famous. This electronic whiteboard buying guide will help you find a suitable model. We also offer a selection of suitable models for your needs and budget.

Guide to purchasing an electronic whiteboard

The umbrella term “electronic whiteboard” can be used to describe the broadest range of devices in terms of budget and features. The simplest devices are a digital smart notebook that is primarily for students. However, the most comprehensive ones look more like smart TVs with collaboration, teaching, and productivity apps. Both teachers and business people can utilize these.

We will attempt to cover both, but we will concentrate on the domestic sphere.

Screen size. The models for the entire class can be as large as 86 inches, emulating classic blackboards. However, individual models are between 8 and 15. If you are considering a large whiteboard in a room, be sure to check the image quality. Considering the diagonal, 4K resolution is a great option. They offer enough detail and sharpness to make it easy to identify the content.

Screen technology refers to panels and lighting systems. These will be familiar with monitors, tablets, and televisions, such as LCD or LED, with their respective variants. These technologies can reduce functions such as viewing quality or interaction (with a finger or a pointer)
