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

Iron-induced deep-level acceptor center in GaN/AlGaN high electron mobility transistors:Energy level and cross section [PDF]
Dynamic transconductance dispersion measurements coupled with device physics simulations were used to study the deep level acceptor center in iron-doped AlGaN/GaN high electron mobility transistors (HEMT).

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