Current Collapse-Free and Self-Heating Performances in Normally Off GaN Nanowire GAA-MOSFETs

open access: yesIEEE Journal of the Electron Devices Society, 2018
Normally off lateral GaN nanowire gate-all-around MOSFETs have been fabricated on the GaN-on-insulator substrate. The dynamic measurement proved that the devices with various nanowire heights exhibit current collapse-free characteristics implying that ...

High transconductance-normally-off GaN MODFETs

open access: yesElectronics Letters, 1995
Normally-off GaN based modulation doped field-effect transistors have been fabricated. The extrinsic transconductance of MODFETs with gate and channel lengths of 3 and 5 /spl mu/m, respectively, is as high as 120 mS/mm. The devices exhibit 300 mA/mm current at a positive gate bias of 3 V. This transconductance value compares very favourably with the 45

Quasi-Normally-Off AlGaN/GaN HEMTs With SiNₓ Stress Liner and Comb Gate for Power Electronics Applications

open access: yesIEEE Journal of the Electron Devices Society, 2020
Recess processes for the fabrication of normally-off GaN HEMTs generally compromise devices’ on-state performance. In this work, recess-free quasi-normally-off GaN HEMTs with a threshold voltage of 0.24 V is realized by local control of two ...

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 ...
