Selectively dry etched of p-GaN/InAlN heterostructures using BCI3-based plasma for normally-off HEMT technology

open access: yesMaterials Research Express, 2021
In this paper, an alternative selective dry etching of p-GaN over InAlN was studied as a function of the ICP source powers, RF chuck powers and process pressures by using inductively coupled plasma reactive ion etching (ICP RIE) system.

Normally-off p-GaN Gated AlGaN/GaN HEMTs Using Plasma Oxidation Technique in Access Region

open access: yesIEEE Journal of the Electron Devices Society, 2020
Normally-off p-GaN gated AlGaN/GaN high electron mobility transistors (HEMTs) were developed. Oxygen plasma treatment converted a low-resistive p-GaN layer in the access region to a high-resistive GaN (HR-GaN); that oxygen plasma treatment used an AlN ...

Normally‐off AlGaN/GaN power tunnel‐junction FETs

open access: yes, 2012
We present normally-off AlGaN/Gan power tunnel-junction FETs (TJ-FETs) with high breakdown voltage, low off-state leakage current and low specific on-resistance. The TJ-FETs exhibit normally-off operation in an otherwise normally-on as-grown sample owing
