Modulation-doped beta-(Al0.2Ga0.8)2O3/Ga2O3 Field-Effect Transistor
Sriram Krishnamoorthy, Zhanbo Xia, Chandan Joishi +8
Modulation-doped heterostructures are a key enabler for realizing high mobility and better scaling properties for high performance transistors. We report the realization of modulat…
Reflective Metal/Semiconductor Tunnel Junctions for Hole Injection in AlGaN UV LEDs
Yuewei Zhang, Sriram Krishnamoorthy, Fatih Akyol +6
In this work, we investigate the use of nanoscale polarization engineering to achieve efficient hole injection from metals to ultra-wide band gap AlGaN, and we show that UV-reflect…
Three-Dimensional Imaging of Individual Point Defects Using Selective Detection Angles in Annular Dark Field Scanning Transmission Electron Microscopy
Jared M. Johnson, Soohyun Im, Jinwoo Hwang
We propose a new scanning transmission electron microscopy (STEM) technique that can realize the three-dimensional (3D) characterization of vacancies, lighter and heavier dopants w…
Interband Tunneling for Hole Injection in III-Nitride Ultra-violet Emitters
Yuewei Zhang, Sriram Krishnamoorthy, Jared M. Johnson +6
Ultra-violet emitters have several applications in the areas of sensing, water purification, and data storage. While the III-Nitride semiconductor system has the band gap region ne…
