Wafer

A team of researchers at the University of Illinois at Urbana-Champaign has advanced gallium nitride (GaN)-on-silicon transistor technology by optimizing the composition of the semiconductor layers that make up the device. Working with industry partners Veeco and IBM, the team created the high elect more

Wacker Chemie AG presented this year’s Alexander Wacker Innovation Award to a project team at Siltronic AG, the Group’s semiconductor division, for developing a novel process used in the production of silicon wafers for high-performance devices. The so-called granular float zone process constitutes more

The application of light for information processing opens up a multitude of possibilities. However, to be able to adequately use photons in circuits and sensors, materials need to have particular optical and mechanical properties. Researchers at the Karlsruhe Institute of Technology (KIT) have now f more

Lighting market has been dominated by light emitting diodes(LEDs), which not only need Ga for for wafer production, but also consume abundant rare-earth elements Y, Ce and Eu. Hybrid-LEDs using organic downconversion materials(ODMs) is a promising candidate technology to save the rare-earth elementa more

Philip Hopkins, a theoretical astrophysicist at the California Institute of Technology in Pasadena, likes to prank his colleagues. An expert in simulating the formation of galaxies, Hopkins sometimes begins his talks by projecting images of his creations next to photos of real galaxies and defying h more
