Prediction of intrinsic magnetism at silicon surfaces could lead to single-spin magnetoelectronics

  • PDF
TechAndComputer (Aug. 27, 2010) — The integration of single-spin magnetoelectronics into standard silicon technology may soon be possible, if experiments confirm a new theoretical prediction by physicists at the Naval Research Laboratory and the University of Wisconsin-Madison. The researchers predict that a family of well-known silicon surfaces, stabilized by small amounts of gold atoms, is intrinsically magnetic despite having no magnetic...

Plastic computer memory device that utilizes electron spin to read and write data: Alternative to traditional semiconductors

  • PDF
TechAndComputer (Aug. 10, 2010) — Researchers at Ohio State University have demonstrated the first plastic computer memory device that utilizes the spin of electrons to read and write data.

An alternative to traditional microelectronics, so-called "spintronics" could store more data in less space, process data faster, and consume less power.

In the August 2010 issue of the journal Nature Materials, Arthur J. Epstein and colleagues describe how...

Graphene exhibits bizarre new behavior well suited to electronic devices

  • PDF
TechAndComputer (July 30, 2010) — Graphene, a sheet of pure carbon heralded as a possible replacement for silicon-based semiconductors, has been found to have a unique and amazing property that could make it even more suitable for future electronic devices.

Physicists at the University of California, Berkeley, and the Lawrence Berkeley National Laboratory (LBNL) have found that when graphene is stretched in a specific way it sprouts nanobubbles...

New quantum state of matter discovered in Heusler compounds: Applications in spintronics, quantum computing and new physical effects

  • PDF
TechAndComputer (July 23, 2010) — For many years, scientists at the Johannes Gutenberg University Mainz (JGU) in Germany have been researching Heusler compounds, which are an important material class for the use in spintronic applications. Over the past few years, new application areas have emerged in the field of renewable energy, such as solar energy and thermoelectrics. And now Heusler compounds are also being considered for future...
