Heterostructure and Interfacial Engineering for Low-Resistance Contacts to Ultra-Wide Bandgap AlGaN
Yinxuan Zhu, Andrew A. Allerman, Chandan Joishi +7
We report on the heterostructure and interfacial engineering of metalorganic chemical vapor deposition (MOCVD) grown reverse-graded contacts to ultra-wide bandgap AlGaN. A record l…
Selective-injection GaN Heterojunction Bipolar Transistors with 275 kA/cm Current Density
Zhanbo Xia, Chandan Joishi, Shahadat H. Sohel +4
We design and demonstrate selective injection GaN heterojunction bipolar transistors that utilize a patterned base for selective injection of electrons from the emitter. The design…
Design and Simulation of a III-Nitride Light Emitting Transistor
Mohammad Awwad, Sheikh Ifatur Rahman, Chandan Joishi +2
This paper describes the design and characteristics of monolithically integrated three-terminal gated III-Nitride light emitting diodes (LEDs) devices. The impact of channel doping…
Selective injection AlGaN/GaN heterojunction bipolar transistors with patterned regrown base contacts
Chandan Joishi, Sheikh Ifatur Rahman, Zhanbo Xia +2
We demonstrate graded AlGaN/GaN heterojunction bipolar transistors (HBTs) with selective injection of minority carriers across a p-GaN base and patterned regrown base contacts. The…
