Delta-doped Beta- Gallium Oxide Field Effect Transistor
Sriram Krishnamoorthy, Zhanbo Xia, Sanyam Bajaj +2
We report silicon delta doping in Gallium Oxide (\b{eta}-Ga2O3) grown by plasma assisted molecular beam epitaxy using a shutter pulsing technique. We describe growth procedures tha…
AlGaN Channel Field Effect Transistors with Graded Heterostructure Ohmic Contacts
Sanyam Bajaj, Fatih Akyol, Sriram Krishnamoorthy +2
We report on ultra-wide bandgap (UWBG) Al0.75Ga0.25N channel metal-insulator-semiconductor field-effect transistors (MISFET) with heterostructure engineered low-resistance ohmic co…
Phonon lasing as a likely mechanism for density-dependent velocity saturation in GaN transistors
Jacob B. Khurgin, Sanyam Bajaj, Siddharth Rajan
We show that density-dependent velocity saturation in a GaN High Electron Mobility Transistor (HEMT) can be related to the stimulated emission of longitudinal optical (LO) phonons.…
Electrical Properties of Atomic Layer Deposited Aluminum Oxide on Gallium Nitride
Michele Esposto, Sriram Krishnamoorthy, Digbijoy N. Nath +3
We report on our investigation of the electrical properties of metal/Al2O3/GaN metal-insulator-semiconductor (MIS) capacitors. We determined the conduction band offset and interfac…
