Sun, Y. (author), Kang, Xuanwu (author), Deng, Shixiong (author), Zheng, Yingkui (author), Wei, Ke (author), Xu, Linwang (author), Wu, Hao (author), Liu, Xinyu (author)We report a high-performance GaN Schottky barrier diode (SBD) on a sapphire substrate with a novel post-mesa nitridation technique and its application in a high-power microwave detection circuit. The fabricated SBD achieved a very high forward current density of 9.19 kA cm-2 at 3 V, a low specific on-resistance (RON,sp) of 0.22 mO cm2 and...journal article 2021

Kang, Xuanwu (author), Sun, Y. (author), Zheng, Yingkui (author), Wei, Ke (author), Wu, Hao (author), Zhao, Yuanyuan (author), Liu, Xinyu (author), Zhang, Kouchi (author)In this brief, a high-performance quasi-vertical GaN Schottky barrier diode (SBD) on sapphire substrate with post-mesa nitridation process is reported, featuring a low damaged sidewall with extremely low leakage current. The fabricated SBD with a drift layer of 1 μm has achieved a very high ON/OFF current ratio (Iscriptscriptstyle ON...journal article 2021
