We designed and fabricated AlGaN/GaN high-electron-mobility transistors (HEMTs) employing both a floating gate (FG) and a field plate (FP), which increase the breakdown voltage of AlGaN/GaN HEMTs significantly without sacrificing forward electric characteristics. The electric field strength at the gate–drain region of the proposed [...]

Photoluminescence-based material quality diagnostics in the manufacturing of CdZnTe ionizing radiation sensors
A photoluminescence method was used for characterization of crystalline perfection of CdZnTe single crystals in the different stages of an up-to-date process of ionizing radiation sensor production. It was shown that the point [...]
Analyses of Five Major LED Manufacturers Vertical Integration Strategies (Part 2)
In part one of these series, LEDinside explored Philips, Osram and Cree’s vertical integration strategies. In the second part of this series we will take a closer look at major Chinese LED companies MLS and Elech-Tech [...]
