Making a good impression: Nanoimprint lithography tests at NIST
In what should be good news for integrated circuit manufacturers, recent studies by the National Institute of Standards and Technology (NIST) have helped resolve two important questions about an emerging microcircuit manufacturing technology called nanoimprint lithography-yes, it can accurately stamp delicate insulating structures on advanced... view more...

Major grant drives forward cost efficient solar power
Whether the search for alternative energy sources is driven by our concern about global fossil fuel supplies or over the atmospheric effects of burning of fossil fuels, the government has laid out its aim to cut carbon dioxide emissions by 60% of 1990 levels by 2050, and aims to over- achieve its goal of sourcing 10% of energy from renewables by... view more...

Bose-Einstein condensation in the solid state
New experimental research shows that half-matter, half-light quasi-particles called polaritons show compelling evidence of Bose-Einstein condensation at the relatively high temperature of 19 degrees Kelvin. view more (2006-09-28)
Testing, radiation testing: Northwestern transistors on space station
Transistors based on a new kind of material created by Northwestern University researchers have been lifted into outer space on the space shuttle Endeavour and attached to the outside of the International Space Station for radiation testing. view more (2008-06-11)
Doping technique brings nanomechanical devices into the semiconductor world
With the help of a device capable of depositing metals an atom at a time in the materials used in computer chips, a team of University of Wisconsin-Madison engineers has successfully blended modern semiconductor technology and nanomachines. view more (2007-09-27)
University of Miami engineer designs stretchable electronics with a twist
Jizhou Song, a professor in the University of Miami College of Engineering and his collaborators Professor John Rogers, at the University of Illinois and Professor Yonggang Huang, at Northwestern University have developed a new design for stretchable electronics that can be wrapped around complex shapes, without a reduction in electronic function. view more (2009-01-22)
Self-assembled nanowires could make chips smaller and faster
Researchers at the University of Illinois have found a new way to make transistors smaller and faster. The technique uses self-assembled, self-aligned, and defect-free nanowire channels made of gallium arsenide. view more (2009-04-21)
Noise measurement may boost cell phone performance
Researchers at the National Institute of Standards and Technology (NIST) and industry collaborators have developed improved methods for accurately measuring very faint thermal "noise"—caused by random motion of electrons—in electronic circuits. view more (2006-06-28)
Stable silicon layer makes flat-panel display cheaper
In a joint project between the Technology Foundation STW and the energy agency Novem at Utrecht University, researchers have developed new silicon layers which are more stable and cheaper than the present amorphous silicon layers. The electronic properties of the present layers in laptop screens and solar cells deteriorate if the material is under... view more... (2002-03-18)
Military imagery analysis assistant
Friend or enemy - what kind of tank or ship can be seen in aerial or satellite photo? The RecceMan identification assistant, which helps recognize the most diverse objects quickly and accurately, is the first interactive image recognition system produced for the German army. view more (2001-12-03)
New 'finFET' promising for smaller transistors, more powerful chips
Purdue University researchers are making progress in developing a new type of transistor that uses a finlike structure instead of the conventional flat design, possibly enabling engineers to create faster and more compact circuits and computer chips. view more (2009-11-11)
Making waves in cancer detection
We`re all familiar with X-rays being used to look inside our bodies. But according to physicists, medical imaging in the future is likely to be based on an as yet unused type of radiation known as terahertz radiation. view more (2002-07-23)
Argonne scientists pinpoint mechanism to increase magnetic response of ferromagnetic semiconductor
When squeezed, electrons increase their ability to move around. In compounds such as semiconductors and electrical insulators, such squeezing can dramatically change the electrical- and magnetic- properties. view more (2009-02-26)
Color sensors for better vision
The car of the future will have lots of smart assistants onboard - helping to park the car, recognize traffic signs and to warn the driver of blind spot hazards. view more (2009-10-06)
Research highlights potential for improved solar cells
A team of Los Alamos researchers led by Victor Klimov has shown that carrier multiplication-when a photon creates multiple electrons-is a real phenomenon in tiny semiconductor crystals and not a false observation born of extraneous effects that mimic carrier multiplication. The research, explained in a recent issue of Accounts of Chemical... view more... (2009-02-11)
Stress management: X-rays reveal Si thin-film defects
Pile-ups, bad on the freeway, also are a hazard for the makers of high-performance strained-silicon (Si) semiconductor devices. view more (2006-07-10)
Tomorrow's green nanofactories
Viruses are notorious villains. They cause serious human diseases like AIDS, polio, and influenza, and can lead to system crashes and data loss in computers. view more (2007-07-10)
Silicon nanowires upgrade data-storage technology
Scientists at the National Institute of Standards and Technology (NIST), along with colleagues at George Mason University and Kwangwoon University in Korea, have fabricated a memory device that combines silicon nanowires with a more traditional type of data-storage. view more (2007-06-11)
Light for the next generation of chips
The semiconductor industry is on the verge of a major technological breakthrough. From 2009 onwards, circuits will be created by exposure to extreme ultraviolet (EUV) rays. Researchers from Aachen were awarded the Stifterverband Science Prize - not only for their EUV source. view more (2004-11-09)
Tiny crystals promise big benefits for solar technologies
Los Alamos National Laboratory scientists have discovered that a phenomenon called carrier multiplication, in which semiconductor nanocrystals respond to photons by producing multiple electrons, is applicable to a broader array of materials that previously thought. view more (2006-01-05)
