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...
Tantalum nitride (TAN) and nichrome (NiCr) are the two most common materials used as thin film resistors (TFR) for monolithic microwave integrated circuits (MMIC) based on AlGaN/GaN high electron mobility tran...
Although outstanding microwave power performance of AlGaN/GaN HEMTs has been reported,drain current collapse is still a problem. In this paper,an experiment was carried out to demonstrate one factor causing the collap...
