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…
Passivation-Free Ga-Polar AlGaN/GaN Recessed-Gate HEMTs on Sapphire with 2.8 W/mm POUT and 26.8% PAE at 94 GHz
Ruixin Bai, Swarnav Mukhopadhyay, Michael Elliott +9
In this work, we demonstrate a passivation-free Ga-polar recessed-gate AlGaN/GaN HEMT on a sapphire substrate for W-band operation, featuring a 5.5 nm Al0.35Ga0.65N barrier under t…
3 kV Monolithic Bidirectional GaN HEMT on Sapphire
Md Tahmidul Alam, Swarnav Mukhopadhyay, Md Mobinul Haque +2
More than 3 kV breakdown voltage was demonstrated in monolithic bidirectional GaN HEMTs for the first time having potential applications in 1200V or 1700V-class novel power convert…
Demonstration of Si-doped Al-rich thin regrown Al(Ga)N films on AlN on sapphire templates with free carrier concentration using close-coupled showerhead MOCVD reactor
Swarnav Mukhopadhyay, Parthasarathy Seshadri, Mobinul Haque +6
Thin Si-doped Al-rich (Al>0.85) regrown Al(Ga)N layers were deposited on AlN on Sapphire template using metal-organic chemical vapor deposition (MOCVD) techniques. The optimization…
High Voltage (~2 kV) field-plated Al0.64Ga0.36N-channel HEMTs
Md Tahmidul Alam, Jiahao Chen, Kenneth Stephenson +5
High voltage (~2 kV) AlGaN-channel HEMTs were fabricated with 64% Aluminum composition in the channel. The average on-resistance was ~75 ohm. mm (~21 miliohm. cm^2) for LGD = 20 mi…
Band alignment of grafted monocrystalline Si (001)/-GaO (010) p-n heterojunction determined by X-ray photoelectron spectroscopy
Jiarui Gong, Jie Zhou, Ashok Dheenan +11
Beta-phase gallium oxide (-GaO) research has gained accelerated pace due to its superiorly large bandgap and commercial availability of large-diameter native substrates.…
Monocrystalline Si/-GaO p-n heterojunction diodes fabricated via grafting
Jiarui Gong, Donghyeok Kim, Hokyung Jang +19
The -GaO has exceptional electronic properties with vast potential in power and RF electronics. Despite the excellent demonstrations of high-performance unipolar devices…
Crack-free high composition (>35%) thick (>30 nm) barrier AlGaN/AlN/GaN HEMT on sapphire with record low sheet resistance
