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 [...]

Graphene-Metal Sandwich Shrinks Electronics

Graphene-Metal Sandwich Shrinks Electronics

Researchers have discovered that creating a graphene-copper-graphene “sandwich” strongly enhances the heat conducting properties of copper, a discovery that could further help in the downscaling of electronics.   The work was led by Alexander A. Balandin, a professor of electrical engineering at the Bourns College of Engineering at the University of California, Riverside and Konstantin [...]

Electronics Based On a 2-D Electron Gas

Electronics Based On a 2-D Electron Gas

Usually, microelectronic devices are made of silicon or similar semiconductors. Recently, the electronic properties of metal oxides have become quite interesting. These materials are more complex, yet offer a broader range of possibilities to tune their properties. An important breakthrough has now been achieved at the Vienna University of Technology: a two dimensional electron gas [...]

Magnet for Fast and Cheap Data Storage

Magnet for Fast and Cheap Data Storage

Professor Rasing, physicist at Radboud University Nijmegen, came up with a new synthetic material for optical data storage.   Optical data storage does not require expensive magnetic materials as synthetic alternatives work just as well. This is the finding of an international team from York, Berlin and Nijmegen, published Thursday February 27 in Applied Physics [...]

Natural 3-D Counterpart to Graphene Discovered: New Form of Quantum Matter

Natural 3-D Counterpart to Graphene Discovered: New Form of Quantum Matter

The discovery of what is essentially a 3D version of graphene — the 2D sheets of carbon through which electrons race at many times the speed at which they move through silicon — promises exciting new things to come for the high-tech industry, including much faster transistors and far more compact hard drives. A collaboration [...]

Potential Future Data Storage at Domain Boundaries

Potential Future Data Storage at Domain Boundaries

Storing more and more in an ever-smaller space — what sounds impossible is in fact just part of the daily routine in information technology, where for decades, increasing amounts of data have been successfully stored on media with ever higher densities. An international team, including researchers from Forschungszentrum Jülich, has now discovered a physical phenomenon [...]
