Move over, silicon: Advances pave way for powerful carbon-based electronics
Bypassing decades-old conventions in making computer chips, Princeton engineers developed a novel way to replace silicon with carbon on large surfaces, clearing the way for new generations of faster, more powerful cell phones, computers and other electronics. view more (2007-12-19)
Hankering for molecular electronics? Grab the new NIST sandwich
The sandwich recipe recently concocted by scientists working at the National Institute of Standards and Technology (NIST) may prove tasty for computer chip designers, who have long had an appetite for molecule-sized electronic components - but no clear way to satisfy it until now. view more (2009-08-27)
A new spin on silicon
For about 40 years, the semiconductor industry has been able to continually shrink the electronic components on silicon chips, packing ever more performance into computers. view more (2005-08-02)
Breakthrough in computer chip design eliminates wires in data transmission
Research slated to appear in the October 2 edition of the Optical Society of America's (OSA) Optics Express will unveil that researchers have created a new laser-silicon hybrid computer chip that can produce laser beams that will make it possible to use laser light rather than wires to send data between chips, removing the most significant... view more...

Carbon nanoribbons could make smaller, speedier computer chips
Stanford chemists have developed a new way to make transistors out of carbon nanoribbons. The devices could someday be integrated into high-performance computer chips to increase their speed and generate less heat, which can damage today's silicon-based chips when transistors are packed together tightly. view more (2008-05-28)
NPL research shows there could be no end in sight for Moore's Law
The fast pace of growing computing power could be sustained for many years to come thanks to new research from the UK's National Physical Laboratory (NPL) that is applying advanced techniques to magnetic semiconductors. view more (2008-12-09)
Researchers get neurons and silicon talking
European researchers have created an interface between mammalian neurons and silicon chips. view more (2006-03-28)
Speed bumps less important than potholes for graphene
For electrical charges racing through an atom-thick sheet of graphene, occasional hills and valleys are no big deal, but the potholes-single-atom defects in the crystal-they're killers. view more (2007-07-13)
New study: Why solar cells lose potency
Commercial products such as laptop computer monitors and solar-powered calculators are constructed from a light-sensitive material with a peculiar problem: When exposed to intense light, it forms defects, reducing the efficiency of the solar cells by 10 to 15 percent. view more (2005-06-20)
UD researchers put 'spin' in silicon, advance new age of electronics
Electrical engineers from the University of Delaware and Cambridge NanoTech have demonstrated for the first time how the spin properties of electrons in silicon--the world's most dominant semiconductor, used in electronics ranging from computers to cell phones--can be measured and controlled. view more (2007-05-21)
Custom-sized microlenses
Optical components have joined the trend towards miniaturization. There have, however, been no methods available thus far to produce custom-sized glass lenses. A new process now enables the low-cost, high-volume manufacture of microlenses with extreme dimensions. view more (2004-08-27)
Nano-sediment highways in catalyst
Dutch chemists have visualised how the porous structure of a zeolite catalyst depends on the production method. Zeolite made with carbon fibres as a template, has particles with straight canals that act as highways for the oil components which must be converted into benzene components. Zeolite is normally given a steam treatment to improve its... view more... (2003-03-21)
A bright future for plastics -- robot 'skin,' flexible laptops and electric posters
With market analysts predicting a ten fold increase in the value of the organic light emitting display industry, from £1.5 billion to £15.5 billion, by 2014, it is no wonder that scientists and governments alike are keen to advance research into "plastic electronics". view more (2008-07-01)
How to make microwaves on a chip to replace X-rays for medical imaging and security
Is microwave radiation the nondestructive imaging technology of the future? Microwaves with frequencies from a few hundred gigahertz (GHz) up to slightly over 1 terahertz (THz), penetrate just a short distance into surfaces without the ionizing damage caused by X-rays. view more (2008-05-30)
Georgia Tech/IBM team demonstrates first 500 GHz silicon-germanium transistors
A research team from IBM and the Georgia Institute of Technology has demonstrated the first silicon-germanium transistor able to operate at frequencies above 500 GHz. view more (2006-06-20)
NRL generates, modulates, and electrically detects pure spin currents in silicon
Scientists at the Naval Research Laboratory (NRL) have generated, modulated and electrically detected a pure spin current in silicon, the semiconductor used most widely in the electronic device industry. view more (2007-12-04)
UW-Madison team invents fast, flexible computer chips on plastic
ew thin-film semiconductor techniques invented by University of Wisconsin-Madison engineers promise to add sensing, computing and imaging capability to an amazing array of materials. view more (2006-07-19)
Cornell researchers test carbon fiber to make tiny, cheap video displays
Engineers who develop microelectromechanical systems (MEMS) like to make their tiny machines out of silicon because it is cheap, plentiful and can be worked on with the tools already developed for making microelectronic circuits. There is just one problem: Silicon breaks too easily. view more (2006-08-23)
Philips and DIMES found the Philips Associated Centre (PACD) at DIMES
Philips and DIMES found the Philips Associated Centre (PACD) at DIMES Towards highly integrated telecommunication function Philips has chosen TU Delft`s Institute for Micro-electronics en Submicron-technology (DIMES) to host a large research programme. The goal of this Philips Associated Centre at Dimes (PACD) is research on the integration of... view more... (2002-01-07)
Creating unconventional metals
The semiconductor silicon and the ferromagnet iron are the basis for much of mankind's technology, used in everything from computers to electric motors. In this week's issue of the journal Nature (August 21st) an international group of scientists, including academic and industrial researchers from the UK, USA and Lesotho, report that they have... view more...
