Future Computers Built from Magnetic ‘Tornadoes’

Magnetic materials form the basis of most hard disc drives as they are able to store data. A team from the University of Sheffield’s Faculty of Engineering have been investigating whether they could also be used to perform calculations, and so take on the role of a computer’s central processing unit (CPU). Lead researcher, Dr [...]

Graphene: When a Doughnut Becomes an Apple

Graphene: When a Doughnut Becomes an Apple

In experiments using the wonder material graphene, ETH researchers have been able to demonstrate a phenomenon predicted by a Russian physicist more than 50 years ago. They analysed a layer structure that experts believe may hold unimagined promise.   Anastasia Varlet works as a doctoral candidate in the research group headed by ETH Professor Klaus [...]

Beyond Silicon: Next Generation Electronic Device

Beyond Silicon: Next Generation Electronic Device

In the consumer electronics industry, the mantra for innovation is higher device performance/less power. Arun Thathachary, a Ph.D. student in Penn State’s Electrical Engineering Department, spends his days and sometimes nights in the cleanroom of the Materials Research Institute’s Nanofabrication Laboratory trying to make innovative transistor devices out of materials other than the standard semiconductor [...]

Breakthrough for IT Using Heusler Materials

Breakthrough for IT Using Heusler Materials

It is the breakthrough that physicists and chemists around the world have long anticipated and it will play a pivotal role in information technology in coming years. Researchers at Johannes Gutenberg University Mainz (JGU) have managed, for the first time, to directly observe the 100 percent spin polarization of a Heusler compound. Heusler alloys are [...]

Playing Pool With Carbon Atoms

Playing Pool With Carbon Atoms

A University of Arizona-led team of physicists has discovered how to change the crystal structure of graphene, more commonly known as pencil ‘lead’, with an electric field, an important step toward the possible use of graphene in microprocessors that would be smaller and faster than current, silicon-based technology.   Graphene consists of extremely thin sheets [...]

New Materials, Electronics Dissolve When Told To

New Materials, Electronics Dissolve When Told To

A medical device, once its job is done, could harmlessly melt away inside a person’s body. Or, a military device could collect and send its data and then dissolve away, leaving no trace of an intelligence mission. Or, an environmental sensor could collect climate information, then wash away in the rain.   It’s a new [...]

Materials for Super-Efficient Nanoelectronics

Materials for Super-Efficient Nanoelectronics

Scientists at the Department of Energy’s SLAC National Accelerator Laboratory and Stanford University have discovered a potential way to make graphene — a single layer of carbon atoms with great promise for future electronics — superconducting, a state in which it would carry electricity with 100 percent efficiency.   Researchers used a beam of intense [...]
