Time evolution of off-state degradation of AlGaN/GaN high electron-mobility transistors [PDF]

open access: yes, 2014
The evolution of AlGaN/GaN high electron-mobility transistors under off-state stress conditions is studied by gate leakage current (Ig) monitoring, electroluminescence (EL), and atomic force microscope (AFM) imaging at room temperature.

Investigation into intermodulation distortion in HEMTs using a quasi-2-D physical model [PDF]

open access: yes, 2001
The need for both linear and efficient pseudomorphic high electron-mobility transistors (pHEMTs) for modern wireless handsets necessitates a thorough understanding of the origins of intermodulation distortion at the device level.

Hot electron modelling of HEMTs [PDF]

open access: yes7th International Workshop on Computational Electronics. Book of Abstracts. IWCE (Cat. No.00EX427), 2001
The hot‐electron two‐dimensional HEMT with recessed gate is modelled by solving the Poisson, current continuity and energy transport equations consistently with the Schrödinger equation using a finite difference scheme. New expressions are used for the energy densities inside and outside the quantum wells.

Reliability Testing of AlGaN/GaN HEMTs Under Multiple Stressors [PDF]

open access: yes, 2011
We performed an experiment on AlGaN/GaN HEMTs with high voltage and high power as stressors. We found that devices tested under high power generally degraded more than those tested under high voltage.

Intentionally Carbon-Doped AlGaN/GaN HEMTs:Necessity for Vertical Leakage Paths [PDF]

open access: yes, 2014
Dynamic ON-resistance (RON) in heavily carbon doped AlGaN/GaN high electron mobility transistors is shown to be associated with the semi-insulating carbon-doped buffer region.

Electron density effects in the modulation spectroscopy of strained and lattice-matched InGaAs/InAlAs/InP high-electron-mobility transistor structures [PDF]

open access: yes, 1996
The effects of the channel electron density on the interband optical transitions of strained (x=0.6 and 0.65) and lattice-matched (x=0.53) InxGa1–xAs/In0.52Al0.48As/InP high-electron-mobility transistor structures have been investigated by ...

Revealing the Mechanism of the Bias Temperature Instability Effect of p-GaN Gate HEMTs by Time-Dependent Gate Breakdown Stress and Fast Sweeping Characterization

open access: yesMicromachines, 2023
The bias temperature instability (BTI) effect of p-GaN gate high-electron-mobility transistors (HEMTs) is a serious problem for reliability. To uncover the essential cause of this effect, in this paper, we precisely monitored the shifting process of the ...
