New computer program automates chip debugging
Fixing design bugs and wrong wire connections in computer chips after they've been fabricated in silicon is a tedious, trial-and-error process that often costs companies millions of dollars and months of time-to-market. view more (2007-11-06)
NRL scientists demonstrate efficient electrical spin injection into silicon
Scientists at the Naval Research Laboratory (NRL) have efficiently injected a current of spin-polarized electrons from a ferromagnetic metal contact into silicon, producing a large electron spin polarization in the silicon. view more (2007-07-17)

Feeling the Heat: Berkeley Researchers Make Thermoelectric Breakthrough in Silicon Nanowires
Energy now lost as heat during the production of electricity could be harnessed through the use of silicon nanowires synthesized via a technique developed by researchers with the U.S. Department of Energy's (DOE) Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) at Berkeley. view more (2008-01-11)
Quantum coherence possible in incommensurate electronic systems
Researchers at the University of Illinois at Urbana-Champaign have demonstrated that quantum coherence is possible in electronic systems that are incommensurate, thereby removing one obstacle in the development of quantum devices. view more (2006-11-03)
Stretchable silicon could be next wave in electronics
Researchers at the University of Illinois at Urbana-Champaign have developed a fully stretchable form of single-crystal silicon with micron-sized, wave-like geometries that can be used to build high-performance electronic devices on rubber substrates. view more (2005-12-16)
Carnegie Mellon scientist confirms liquid-liquid phase transition in silicon
Using rigorous computer calculations, researchers from Carnegie Mellon University and the Carnegie Institution of Washington have established evidence that supercooled silicon experiences a liquid-liquid phase transition, where at a certain temperature two different states of liquid silicon exist. view more (2009-03-17)
Vise squad: Putting the squeeze on a crystal leads to novel electronics
A clever materials science technique that uses a silicon crystal as a sort of nanoscale vise to squeeze another crystal into a more useful shape may launch a new class of electronic devices that remember their last state even after power is turned off. view more (2009-05-11)
New laser technique that strips hydrogen from silicon surfaces
A team of researchers have achieved a long-sought scientific goal: using laser light to break specific molecular bonds. The process uses laser light, instead of heat, to strip hydrogen atoms from silicon surfaces, a key step in the manufacture of computer chips and solar cells. view more (2006-05-19)
UCLA Engineering Announces Breakthrough in Silicon Photonics Devices
Building on a series of recent breakthroughs in silicon photonics, researchers at the UCLA Henry Samueli School of Engineering and Applied Science have developed a novel approach to silicon devices that combines light amplification with a photovoltaic — or solar panel — effect. view more (2006-06-29)
AN ELEMENT OF UNCERTAINTY
Professor Alan Murray and Dr Martin Reekie of the Department of Electronics & Electrical Engineering aim to develop small analogue circuits which will do what conventional computers find difficult - to represent the element of uncertainty which is present in most physical and biological processes and is an intrinsic feature of many natural... view more...

Purdue simulation to help merge molecules with silicon electronics
Engineers at Purdue University have created a nanotech simulation tool that shows how current flows between silicon atoms and individual molecules to help researchers design "molecular electronic" devices for future computers and advanced sensors. view more (2005-08-18)
From trees to high-performance ceramics
When a racing driver brakes, the discs and linings become red-hot. These parts are commonly made of carbon-fiber-reinforced carbon and are black at moderate temperatures. Car manufacturers and their suppliers would dearly like to extend the use of these special brake pads and other hard-wearing parts developed for racing vehicles to perfectly... view more...
