New materials mimic electronic properties of graphene in 3D

By - January 22, 2014 3 Pictures
Exciting times are ahead in the high-tech industries with the discovery by three independent groups that a new class of materials mimic the special electronic properties of graphene in 3D. Research into these superfast massless charge carriers opens up a wide range of potential applications in electronics, including smaller hard drives with more storage capacity, faster transistors and more efficient optical sensors.

Spintronics used to create 3D microchip

By - February 1, 2013 2 Pictures
A major obstruction to the development of practical 3D microchips is moving data and logic signals from one layer of circuitry to another. This can be done with conventional circuitry, but is quite cumbersome and generates a good deal of heat inside the 3D circuit. Physicists at the University of Cambridge have now developed a spintronic shift register that allows information to be passed between different layers of a 3D microchip. Read More

New “spintronic” OLEDs join next-generation display technology mix

By - July 15, 2012 1 Picture
We’ve seen a number of next-generation display technologies emerge in recent years, such as Sony’s “Crystal LED,” Uni-Pixel’s time-multiplexed optical shutter (TMOS) technology, and quantum dot LED (QLED) display technology from LG and QD Vision, and now there’s another one to add to the mix. While displays based on the new “spintronic” OLED technology invented by physicists at the University of Utah are still some years off, the researchers say they should be brighter, cheaper and more environmentally friendly than the LEDs found in the current crop of TVs, computer displays, traffic lights and other electronic devices.

Nanoscale magnetic waves could replace microwave technology

By - September 8, 2011 1 Picture
The microwave technology used in applications such as mobile phones and wireless networks may be on its way to being replaced - with parts that are smaller, less expensive, and that consume less resources. Instead of microwaves, devices of the future may use spin waves, which are nanoscale magnetic waves. For almost ten years, it has been theorized that spin waves could be propagated using magnetic nanocontacts. Recently, scientists from the University of Gothenburg and the Royal Institute of Technology, Sweden, became the first people to demonstrate that the theory meshes with observable phenomena.

'Racetrack memory' could be 100,000 times faster than hard drives

By - November 15, 2010 2 Pictures
Tired of waiting for your computer to boot up? Within five to seven years, you may no longer have to. That’s the estimated amount of time it will take to bring Racetrack Memory to market. Racetrack is a proposed new shock-proof system that is said to be 100,000 times faster than current hard drives, while also being 300 times more energy-efficient. Although it incorporates cutting-edge nanotechnology, it’s based on the same principles as the humble VHS videotape. Read More

Putting waste heat from electronics to good use

By - September 28, 2010 1 Picture
Researchers at two different institutions have recently announced the development of technologies for converting waste heat from electronics into something useful. At the California Institute of Technology (Caltech), they’ve created a silicon nanomesh film that could collect heat from electric appliances such as computers or refrigerators and convert it to electricity. Meanwhile, their colleagues at Ohio State University (OSU) have been working with a semiconducting material that has the capacity to turn waste heat from computers into additional processing power.

Latest spintronics breakthrough detects flow of spinning electrons in real time

By - August 24, 2010 1 Picture
Spin electronics, or “spintronics” promises to revolutionize computing. We’ve covered numerous breakthroughs in the field including controlling the spin of electrons, manipulating single electrons independently, and the first plastic spintronic computer memory device. However, one major hurdle for spintronics researchers has been the difficulty in detecting the flow of spinning electrons in real time. The discovery of a new way to recognize currents of spinning electrons within a semiconductor changes that and could lead the way to the development of superior computers and electronics. Read More

Researchers demonstrate first plastic spintronic computer memory device

By - August 10, 2010 1 Picture
Spintronics – or spin electronics – is an emerging technology that exploits the intrinsic spin of the electron rather than its charge, as is the case with current electronic devices. The technology promises microelectronic devices that can store more data in less space, process data faster, and consume less power. Researchers at Ohio State University (OSU) have now demonstrated the first plastic memory device that utilizes the spin of electrons to read and write data. Read More
