Harvard University engineers demonstrate quantum cascade laser nanoantenna
In a major feat of nanotechnology engineering researchers from Harvard University have demonstrated a laser with a wide-range of potential applications in chemistry, biology and medicine. view more (2007-10-23)
Hybrid semiconductors show zero thermal expansion; could lead to hardier electronics and optoelectronics
The fan in your computer is there to keep the microprocessor chip from heating to the point where its component materials start to expand, inducing cracks that interrupt the flow of electricity - and not incidentally, ruin the chip. view more (2007-12-20)
Physicists step closer to understanding origin of the universe
The world's largest particle detector is nearing completion following the construction of its 'endcap' at the University of Liverpool. view more (2006-02-22)
New 'near-field' radiation therapy promises relief for overheating laptops
Our modern age has become accustomed to regular improvements in information technology, says Slava Rotkin, but these advances do not come without a cost. view more (2009-04-14)
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)
UCI scientists use nanotechnology to create world's fastest method for transmitting information in cell phones and computers
UC Irvine scientists in The Henry Samueli School of Engineering have demonstrated for the first time that carbon nanotubes can route electrical signals on a chip faster than traditional copper or aluminum wires, at speeds of up to 10 GHz. view more (2005-06-10)
Peering Inside Nanowires
Semiconductor nanowires - tiny wires with a diameter as small as a few billionths of a meter - hold promise for devices of the future, both in technology like light-emitting diodes and in new versions of transistors and circuits for next generation of electronics. view more (2009-04-02)
RC-LEDs - Super-fast light sources suitable for data transfer
Resonance-cavity light-emitting diodes (RC-LEDs) are a new type of light source which produces very intense light from quantum wells located in a microcavity. As light sources, RC-LEDs are classified as something between laser diodes and conventional light-emitting diodes (LEDs). The advantages of RC-LEDs compared with conventional LEDs include a... view more... (2000-02-25)
Ancient diatoms lead to new technology for solar energy
Engineers at Oregon State University have discovered a way to use an ancient life form to create one of the newest technologies for solar energy, in systems that may be surprisingly simple to build compared to existing silicon-based solar cells. view more (2009-04-09)
A sonic boom in the world of lasers
It was an idea born out of curiosity in the physics lab, but now a new type of 'laser' for generating ultra-high frequency sound waves instead of light has taken a major step towards becoming a unique and highly useful 21st century technology. view more (2009-06-18)
Solar energy: Charged for the future
Once regarded as costly and impractical, solar technology is now poised to play a larger role in the future, thanks to new developments that could result in lower costs and improved efficiency. view more (2006-09-11)
Weizmann Institute Scientists Find New 'Quasiparticles'
Weizmann Institute physicists have demonstrated, for the first time, the existence of 'quasiparticles' with one quarter the charge of an electron. This finding could be a first step toward creating exotic types of quantum computers that might be powerful, yet highly stable. view more (2008-06-03)
Physicists tailor magnetic pairings in nanoscale semiconductors
Electrons love to zip around metals such as copper, especially if the metal is cooled to temperatures near absolute zero. But if they encounter a magnetic atom (say, iron) during their travels, the electrons will try to "screen," or cancel out, the magnetic atom's spin alignment by pairing with it. This pairing modifies the flow of... view more... (2007-03-15)
In diatom, scientists find genes that may level engineering hurdle
Denizens of oceans, lakes and even wet soil, diatoms are unicellular algae that encase themselves in intricately patterned, glass-like shells. Curiously, these tiny phytoplankton could be harboring the next big breakthrough in computer chips. view more (2008-01-22)
McGill physicists find a new state of matter in a 'transistor'
McGill University researchers have discovered a new state of matter, a quasi-three- dimensional electron crystal, in a material very much like those used in the fabrication of modern transistors. view more (2008-10-22)
Moving a bit nearer to a quantum computer
By the time you`ve had your new computer for six months, much faster processors will already be on the market. But there is a limit to how fast conventional computers can become. This is because computers process information in a step-by-step fashion, carrying out each part of the process in turn. To make things work really fast, we need to build... view more... (2002-07-23)
UK researchers find way to reduce power consumption of transistors in computer chips
University of Kentucky researchers have discovered a means of reducing gate leakage current of transistors in computer chips that will permit chip producers to continue developing more efficient and powerful chips with reduced power consumption. view more (2005-12-07)
Carbon nanotubes outperform copper nanowires as interconnects
Researchers at Rensselaer Polytechnic Institute have created a road map that brings academia and the semiconductor industry one step closer to realizing carbon nanotube interconnects, and alleviating the current bottleneck of information flow that is limiting the potential of computer chips in everything from personal computers to portable music... view more...

UA Physicists Discover 'Super Crystals' in a Semiconductor
University of Arizona physicists have discovered that "super crystals" -- crystals which are hundreds to thousands times larger than conventional crystals -- exist in certain organic semiconducting solids. view more (2007-08-17)
Toward cheaper imaging systems for identifying concealed weapons on the human body
Electrical engineers from UC San Diego have created high-performance W-Band silicon-germanium (SiGe) radio frequency integrated circuits (RFICs) for passive millimeter-wave imaging. view more (2009-06-09)
