Fine-tuned Normalizing Flows for ALICE Zero Degree Calorimeter Fast Simulation
Emilia Majerz, Jacek Otwinowski, Witold Dzwinel +1
Simulating the ALICE Zero Degree Calorimeter (ZDC) neutron detector responses at the LHC is computationally expensive, requiring complex Monte Carlo chains. We develop a generative…
A Promising Ohmic Contacts Approach for High-Al AlxGa1-xN (x>0.6) Channel HEMTs with AlN/GaN Digital Alloy Channel
Tariq Jamil, Abdullah Al Mamun Mazumder, S M Tazbiul Hasan +9
In this paper we report a novel ohmic contact formation scheme for Extreme Bandgap (EBG) AlxGa1-xN (x>0.6) channel HEMTs with undoped barrier layers. Our approach consists of using…
Scaled Ultra-Wide Bandgap AlGaN Polarization-Graded FET with Ultra-thin Buffer Layer
Yinxuan Zhu, Ashley Wissel-Garcia, Kidus Guye +12
We report on the design and demonstration of ultra-wide bandgap AlGaN polarization-graded field effect transistors with ultra-thin channels to enable excellent current density and…
High Breakdown Electric Field (> 5 MV/cm) in UWBG AlGaN Transistors
Seungheon Shin, Hridibrata Pal, Jon Pratt +8
We report on the design and demonstration of ultra-wide bandgap (UWBG) AlGaN-channel metal-insulator heterostructure field effect transistors (HEFTs) for high-power, high-frequency…
Energy Bands and Breakdown Characteristics in Al2O3/UWBG AlGaN Heterostructures
Seungheon Shin, Kyle Liddy, Yinxuan Zhu +5
We report on energy bands and breakdown characteristics of Al2O3 dielectrics on ultra-wide bandgap (UWBG) AlGaN heterostructures. Metal-dielectric-semiconductor structures are impo…
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…
