800 $^{\circ}$ C Air-Ambient Operation of Extreme-Bandgap Al $_{x}$ Ga $_{1 - x}$ N (x>0.6) Digital and Random-Alloy Channel HEMTs

Abdullah Al Mamun Mazumder, Tariq Jamil, Mafruda Rahman +11

This work demonstrates the high-temperature (room to 800 $^{\circ}$ C) operation of thin Al $_{0.62}$ Ga $_{0.38}$ N digital alloy (DA) short-period superlattice (SPSL), and random alloy…

A Promising Ohmic Contacts Approach for High-Al AlxGa1-xN (x>0.6) Channel HEMTs with AlN/GaN Digital Alloy Channel

Tariq Jamil, Abdullah Al Mamun Mazumder, S M Tazbiul Hasan +9

In this paper we report a novel ohmic contact formation scheme for Extreme Bandgap (EBG) AlxGa1-xN (x>0.6) channel HEMTs with undoped barrier layers. Our approach consists of using…
