In this work, we investigated the time-dependent dielectric breakdown (TDDB) characteristics of normally-off AlGaN/GaN gate-recessed metal−insulator−semiconductor (MIS) heterostructure field effect transistors (HFETs) submitted to proton irradiat

We investigated the low-temperature operation of normally-off AlGaN/GaN heterostructure field-effect-transistors (HFETs) with gate-recessed metal-oxidesemiconductor (MOS) structure and normally-on Schottky-gate high-electron-mobility-transistors (HEM

Proton irradiation at 5 MeV was performed on normally-off p-AlGaN gate AlGaN/GaN high electron mobility transistors (HEMTs). The increase of on-resistance and the degradation of subthreshold characteristics were observed after irradiation. The reduct

Increased demand for compact devices leads to rapid development of miniaturized digital cameras. However, conventional camera modules contain multiple lenses along the optical axis to compensate for optical aberrations that introduce technical challe

Proton irradiation at 5 MeV was performed on normally-off AlGaN/GaN metal-insulator-semiconductor heterostructure field effect transistors and normally-on Schottky high electron mobility transistors fabricated on the same GaN-on-Si wafer. The positiv

Normally-off AlGaN/GaN metal-oxide-semiconductor heterostructure field effect transistors have been fabricated and characterised for non-volatile memory operation. 2 nm-thickness AlGaN barrier layer was obtained by gate recess process using inductive

We have performed reverse gate bias stress tests on AlGaN/GaN-on-Si Heterostructure FETs (HFETs). The shift of threshold voltage (Vth) and the reduction of on-current were observed from the stressed devices. These changes of the device parameters wer
