Journal ArticleDOI
High-temperature performance of AlGaN/GaN HFETs on SiC substrates
TL;DR: In this article, the performance results of AlGaN-GaN Heterostructure Field Effect Transistors (HFETs) grown on SiC substrates are reported, and the maximum transconductance of these devices was 142 mS/mm and the source-drain current was as high as 0.95 A/mm.
Journal ArticleDOI
Investigation of the mechanism for Ohmic contact formation in Al and Ti/Al contacts to n-type GaN
TL;DR: In this paper, the authors showed that the mechanism for Ohmic contact formation in Ti/Al contacts annealed in the 400-600°C range includes Ti reducing the GaN native oxide and an Al-Ti intermetallic coming into intimate contact with GaN.
Journal ArticleDOI
Schottky barrier properties of various metals on n-type GaN
TL;DR: Schottky barriers of Ti, Cr, Au, Pd, Ni and Pt on n-type GaN epitaxial layers grown by low-pressure metal-organic chemical vapour deposition on sapphire have been fabricated and characterized as mentioned in this paper.
Journal ArticleDOI
Piezoresistive effect in wurtzite n‐type GaN
TL;DR: In this paper, the authors measured the piezoresistive effect in the n-type wurtzite GaN films and found that the 3-5 μm thick GaN layers were deposited slightly off axis over basal plane sapphire substrates.
Journal ArticleDOI
The late increase in intracellular free radical oxygen species during apoptosis is associated with cytochrome c release, caspase activation, and mitochondrial dysfunction.

TL;DR: Results indicate that the late ROS production is associated with increased PT pore opening and decreased Δψm, and GSH, events associated with caspase activation and cytochrome c release.
