Veeco Instruments Inc. announced today the launch of the new TurboDisc® K475i™ Arsenic Phosphide (As/P) Metal Organic Chemical Vapor Deposition (MOCVD) System for the production of red, orange, yellow (R/O/Y) light emitting diodes (LEDs), as well as multi-junction III-V solar cells, laser diodes and transistors.
Nanoscientists at the Univeristy of Alicante have modified a commonly-used compound, titanium dioxide, turning it from white to black to boost its efficiency. And they have done so in a way that improves on existing methods, making environmental applications a real possibility.
Heterostructures formed by different three-dimensional semiconductors form the foundation for modern electronic and photonic devices. Now, University of Washington scientists have successfully combined two different ultrathin semiconductors — each just one layer of atoms thick and roughly 100,000 times thinner than a human hair — to make a new two-dimensional heterostructure with potential uses in clean energy and optically-active electronics. The team, led by Boeing Distinguished Associate Professor Xiaodong Xu, announced its findings in a paper published Feb. 12 in the journal Science.
Researchers at the Paul Scherrer Institute have produced large numbers of detailed models of the Matterhorn, each one less than a tenth of a millimetre in size. With this, they demonstrated how 3-D objects so delicate could be mass-produced. Materials whose surface is covered with a pattern of such tiny 3-D structures often have special properties. What nature has exploited for so long could be instructive for a number of industrial applications. Many snakes glide over sand aided by 3-D structures on their skin that significantly reduce friction. Along the same lines, machine parts could be furnished with a comparable structure, thereby minimizing wear and tear.
After more than half a decade of speculation, fabrication, modeling and testing, an international team of researchers led by Drexel University’s Yury Gogotsi, PhD , and Patrice Simon, PhD, of Paul Sabatier University in Toulouse, France, have confirmed that their process for making carbon films and micro-supercapacitors will allow microchips and their power sources to become one and the same.
Have you ever noticed that when heated a film of oil in a pan doesn’t remain completely flat? Instead, it forms a wavy pattern that resembles the exterior of an orange. These sorts of deformations inspired a group of researchers at the Technical University of Darmstadt, in Germany, to explore whether they could be used to improve and streamline microfabrication processes.
A team of researchers from North Carolina State University have determined a new phase of boron nitride (Q-BN), which plays a vital role in both electronic displays and manufacturing tools. The team have come up with a new method for forming cubic boron nitride (c-BN) at ambient air pressure and temperatures. This method is used for a wide range of application, such as the develop,emt modern power grid technologies.
Along with the fast development of modern information technology, charge-based memories, such as DRAM and flash memory, are being aggressively scaled down to meet the current trend of small size devices.
Scientists from Rice University have developed a new nanotube-based outer conductor that helps reduce 50% weight of common coaxial cables.
Origami, the ancient art of paper folding, may soon provide a foundation for antennas that can reconfigure themselves to operate at different frequencies, microfluidic devices whose properties can change in operation – and even heating and air-conditioning ductwork that adjusts to demand.
