Integration of p-type Cr2O3 on Ultra-Wide Bandgap AlGaN PolFETs with 2.5 kV Breakdown Voltage
Jonathan Pratt, Yizheng Liu, Ijaas Mohamed +8
We demonstrate UWBG AlGaN polarization-graded field-effect transistors (PolFETs) incorporating room-temperature sputtered p-type oxide Cr2O3 as a P-N heterojunction gate, enabling…
VBr >10 kV E-Beam/Sputtered Vertical NiOx/(011) β-Ga2O3 HJDs with PFOM >2.3 GW/cm2
Yizheng Liu, Carl Peterson, Chinmoy Nath Saha +2
Beta-gallium oxide (β-Ga2O3) holds enormous potential for medium voltage range power electronic applications. This work reports VBr > 10 kV/Ron,sp = 43 mΩ*cm2 class edge terminated…
Evidence of Micron-Scale Ion Damage in (010), (110), and (011) Epitaxial Layers
Carl Peterson, Chinmoy Nath Saha, Yizheng Liu +2
We report on the experimental observation of up to 11.5 deep charge depletion in (010), (110), and (011) epitaxial layers due to ion damage from sputtering and ind…
