We present a reliable process and design technique for realizing high voltage AlGaN/GaN hetero-junction field effect transistors (HFETs) on Si substrates with very low and stable off-state leakage current characteristics. In this work, we have invest

We present the development of an Au-free ohmic contact metallization for high voltage GaN-based high electron mobility transistors (HEMTs). In this letter, low contact resistance (0.81 Ω·mm) is obtained for Au-free electrodes on AlGaN/GaN HEMT stru

InAs/InGaAsP quantum dots (QD) grown on InP substrates show strong photoluminescence (PL) signals, with peaks from 1.4 to 1.6 µm at room temperature. Time-resolved PL measurements reveal that carrier lifetimes are the same across the entire PL band

We have investigated the effects of surface passivation on off-state leakage current and current collapse effects of high-voltage GaN-on-Si hetero-junction field effect transistors (HFETs) by using low pressure chemical vapor deposition (LPCVD) of si
