Abstract

We proposed circular AlGaN/GaN schottky barrier diode, which has no mesa structure near the current path. Proposed device showed low leakage current of 10 nA/mm at -100 V while that of the rectangular device was 34 nA/mm at the same condition. Proposed circular AlGaN/GaN SBD showed high forward current of 88.61 mA at 3.5 V while that of the conventional device was 14.1 mA at the same condition.
