Vishay Intertechnology has introduced a series of high-power, surface-mount, precision non-magnetic thin film chip resistors. The PCNM series offers power ratings of 2 and 6W in compact 1206 and 2512 case sizes, respectively. These high power ratings make the devices suited for use in power supplies for telecomms, medical and military equipment and instrumentation.

A novel 3D solar cell design developed at Georgia Tech will soon get its first testing in space aboard the International Space Station. An experimental module containing 18 test cells was launched to the ISS, and will be installed on the exterior of the station to study the cells’ performance and their ability to withstand the rigors of space. In addition to testing the 3D format, the module will also study a low-cost copper-zinc-tin-sulfid...

ITO and IGZO targets are widely used for coating glass and display surfaces. Since not all the material is consumed in the deposition process, Indium Corporation reclaims the unused portions of the targets and any indium left in the deposition chambers or on the equipment.

University of Utah materials science and engineering associate professor Mike Scarpulla wants to shed light on semiconductors—literally.Scarpulla and senior scientist Kirstin Alberi of the National Renewable Energy Laboratory in Golden, Colorado, have developed a theory that adding light during the manufacturing of semiconductors—the materials that make up the essential parts of computer chips, solar cells and LEDs—can reduce de...

Among the unusual properties of graphene, one of the most exciting and least understood is the additional degree of freedom experienced by electrons.It is called the pseudospin and it determines the probability to find electrons on neighbouring carbon atoms. The possibility to control this degree of freedom would allow for new types of experiments, but potentially also enable to use it for electronic applications.

Science fiction is inching closer to reality with the development of revolutionary self-propelling liquid metals - a critical step towards future elastic electronics.While building a shape-shifting liquid metal T-1000 Terminator may still be far on the horizon, the pioneering work by researchers at RMIT University in Melbourne, Australia, is setting the foundation for moving beyond solid state electronics towards flexible and dynamically reconfig...

Researchers use simulations to identify previously undiscovered semiconductors with promising attributes for optical and electronic applications. A nitride among those proposed has been successfully fabricated using high-pressure synthesis and is found to emit red light. The discovery of new semiconducting materials is a scientifically and technologically important issue; state researchers in Japan in a recent report.

Industrial cooking, heating and drying processes will benefit from replacing decades old technology with modern electronic RF energy systems based on the latest GaN-on-Si technology, writes Sally Ward-Foxton.

CoorsTek, a supplier of engineered ceramics, will unveil its enhanced Gallium Nitride on Silicon (GaN-on-Si) epiwafers at the International Symposium on Power Semiconductor Devices and ICs (ISPSD) in Prague, Czech Republic.

Scientists at The Australian National University (ANU) have improved the performance of tiny lasers by adding impurities, in a discovery which will be central to the development of low-cost biomedical sensors, quantum computing, and a faster internet. Researcher Tim Burgess added atoms of zinc to lasers one hundredth the diameter of a human hair and made of gallium arsenide - a material used extensively in smartphones and other electronic devices...
