First principles study of hBN-AlN short-period superlattice heterostructures
Catalin D. Spataru, Mary H. Crawford, Andrew A. Allerman
We report a theoretical study of the structural, electronic and optical properties of hBN-AlN superlattice heterostructures (SL) using a first-principles approach based on standard…
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…
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…
