In this paper,we investigated the effect of post-gate annealing(PGA)on reverse gate leakage and the reverse bias reliability of Al_(0.23)Ga_(0.77)N/GaN high electron mobility transistors(HEMTs).We found that the Poole...
The DC and RF performance of 30 nm gate length enhancement mode (E-mode) InAlN/AIN/GaN high electron mobility transistor (HEMT) on SiC substrate with heavily doped source and drain region have been inves- tigated ...
AlGaN/GaN high electron mobility transistors(HEMTs)with high performance were fabricated and characterized.A variety of techniques were used to improve device performance,such as AlN interlayer,silicon nitride passi...

This paper focuses on how to reduce the gate leakage current caused by plasma dry etching. X-ray photoelectron spectroscopy (XPS) is employed to measure the AlGaN surface before and after etching. N vacancies are in...
We propose and fabricate an A1GaN/GaN high electron mobility transistor (HEMT) on sapphire substrate using a new kind of electron beam (EB) lithography layout for the T-gate. Using this new layout,we can change th...
