Single-crystalline high-quality beta-Ga2O3 pseudo-substrate on sapphire through sputtering for epitaxial deposition
Guangying Wang, Shuwen Xie, William Brand +10
Solid-phase epitaxy (SPE) of beta-Ga2O3 thin films by radio-frequency (RF) sputtering and then crystallized through high-temperature post-deposition annealing is employed on sapphi…
Low Resistance Ohmic Contact On Epitaxial MOVPE-grown -GaO and -(AlGa) O Films
Fikadu Alema, Carl Peterson, Arkka Bhattacharyya +3
We report on the realization of record low resistance Ohmic contacts to MOVPE-grown heavily Si-doped -GaO and -(AlGa) O epitaxial films. Transfer le…
4.4 kV -GaO Power MESFETs with Lateral Figure of Merit exceeding 100 MW/cm
Arkka Bhattacharyya, Shivam Sharma, Fikadu Alema +7
Field-plated (FP) depletion-mode MOVPE-grown -GaO lateral MESFETs are realized with superior reverse breakdown voltages and ON currents. A sandwiched SiN dielectric…
Multi-kV class -GaO MESFETs with a Lateral Figure of Merit up to 355 MW/cm
Arkka Bhattacharyya, Praneeth Ranga, Saurav Roy +5
We demonstrate over 3 kV gate-pad-connected field plated (GPFP) -GaO lateral MESFETs with high lateral figure of merit (LFOM) using metalorganic vapor phase epitaxy (MOV…
Polarization-mediated Debye-screening of surface potential fluctuations in dual-channel AlN/GaN high electron mobility transistors
David A. Deen, Ross Miller, Andrei Osinsky +5
A dual-channel AlN/GaN/AlN/GaN high electron mobility transistor (HEMT) architecture is proposed, simulated, and demonstrated that suppresses gate lag due to surface-originated tra…
