First Graphene-Based Flexible Display

First Graphene-Based Flexible Display

A flexible display incorporating graphene in its pixels’ electronics has been successfully demonstrated by the Cambridge Graphene Centre and Plastic Logic, the first time graphene has been used in a transistor-based flexible device.   The partnership between the two organisations combines the graphene expertise of the Cambridge Graphene Centre (CGC), with the transistor and display [...]

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 [...]

New Characteristics of Complex Oxide Surfaces

New Characteristics of Complex Oxide Surfaces

A novel combination of microscopy and data processing has given researchers at the Department of Energy’s Oak Ridge National Laboratory an unprecedented look at the surface of a material known for its unusual physical and electrochemical properties.   The research team led by ORNL’s Zheng Gai examined how oxygen affects the surface of a perovskite [...]

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 [...]
