Experimental Observation of High Intrinsic Thermal Conductivity of AlN
Zhe Cheng, Yee Rui Koh, Abdullah Mamun +17
AlN is an ultra-wide bandgap semiconductor which has been developed for applications including power electronics and optoelectronics. Thermal management of these applications is th…
Lateral Heterojunction BaTiO3/AlGaN Diodes with >8MV/cm Breakdown Field
Towhidur Razzak, Hareesh Chandrasekar, Kamal Hussain +11
In this paper, we report enhanced breakdown characteristics of Pt/BaTiO3/Al0.58Ga0.42N lateral heterojunction diodes compared to Pt/Al0.58Ga0.42N Schottky diodes. BaTiO3, an extrem…
Compositionally graded contact layers for MOCVD grown high Al-content AlGaN transistors
Towhidur Razzak, Seongmo Hwang, Antwon Coleman +7
In this letter, we design and demonstrate an improved MOCVD grown reverse Al-composition graded contact layer to achieve low resistance contact to MOCVD grown ultra-wide bandgap (U…
Scattering, weak localization and Shubnikov-de Haas oscillation in high carrier density AlInN/GaN heterostructures
Leizhi Wang, Ming Yin, Asif Khan +4
We provide the first observation of weak localization in high carrier density two-dimensional electron gas in AlInN/GaN heterostructures; at low temperatures and low fields the con…
