Hot LO Phonon-Induced RF Nonlinearity in GaN High-Electron-Mobility Transistors
Ankan Ghosh Dastider, Matt Grupen, Nicholas C. Miller +1
Hot longitudinal optical (LO) phonons in GaN have recently been identified as a major factor degrading the DC performance of GaN high-electron-mobility transistors (HEMTs) by 30-60…
Physics-based Full-band GaN High-Electron-Mobility Transistor Simulation Suggests Upper Bound of LO Phonon Lifetime
Ankan Ghosh Dastider, Matt Grupen, Ashwin Tunga +1
Intrinsic limits to device performance arise from fundamental material properties that define the best achievable operation, independent of engineering constraints. In GaN high-ele…
Topological, or Non-topological? A Deep Learning Based Prediction
Ashiqur Rasul, Md Shafayat Hossain, Ankan Ghosh Dastider +3
Prediction and discovery of new materials with desired properties are at the forefront of quantum science and technology research. A major bottleneck in this field is the computati…
Privacy-Aware Activity Classification from First Person Office Videos
Partho Ghosh, Md. Abrar Istiak, Nayeeb Rashid +5
In the advent of wearable body-cameras, human activity classification from First-Person Videos (FPV) has become a topic of increasing importance for various applications, including…
