Design and Demonstration of Ultra Wide Bandgap AlGaN Tunnel Junctions
Yuewei Zhang, Sriram Krishnamoorthy, Fatih Akyol +4
Ultra violet light emitting diodes (UV LEDs) face critical limitations in both the injection efficiency and light extraction efficiency due to the resistive and absorbing p-type co…
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…
Design of P-Type Cladding Layers for Tunnel-Injected UVA Light Emitting Diodes
Yuewei Zhang, Sriram Krishnamoorthy, Fatih Akyol +4
We discuss the engineering of p-AlGaN cladding layers for achieving efficient tunnel-injected III-Nitride ultraviolet light emitting diodes (UV LEDs) in the UV-A spectral range. We…
Effect of optical phonon scattering on the performance of GaN transistors
Debdeep Jena, Siddharth Rajan
A model based on optical phonon scattering is developed to explain peculiarities in the current drive, transconductance, and high speed behavior of short gate length GaN transistor…
