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…
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…
Electrostatic Engineering using Extreme Permittivity Materials for Ultra-wide Bandgap Semiconductor Transistors
Nidhin Kurian Kalarickal, Zixuan Feng, A F M Anhar Uddin Bhuiyan +7
The performance of ultra-wide band gap materials like -GaO is critically dependent on achieving high average electric fields within the active region o…
Probing charge transport and background doping in MOCVD grown (010) -GaO
Zixuan Feng, A F M Anhar Uddin Bhuiyan, Zhanbo Xia +8
A new record-high room temperature electron Hall mobility ( at ) for -Ga2O3 is demonstrated in the unin…
High electron density modulation doping using ultra-thin (1 nm) spacer layer
Nidhin Kurian Kalarickal, Zhanbo Xia, Joe Mcglone +5
We report on the design and demonstration of modulation doped heterostructures to achieve high sheet charge density. The use of a thin spacer…
Lateral Heterojunction BaTiO3/AlGaN Diodes with >8MV/cm Breakdown Field
Towhidur Razzak, Hareesh Chandrasekar, Kamal Hussain +11
In this paper, we report enhanced breakdown characteristics of Pt/BaTiO3/Al0.58Ga0.42N lateral heterojunction diodes compared to Pt/Al0.58Ga0.42N Schottky diodes. BaTiO3, an extrem…
