摘要：
Utilizing hydrogen plasma treatment and con-trolled diffusion, a junction termination extension (JTE) structure for vertical gallium nitride (GaN) p-n diode with gradient hole density (GHD) is spontaneously formed based on the selective area partial passivation of Mg acceptors with hydrogen. The reverse bias for the quasi-vertical GaN-on-Si p-n diodes to reach a leakage current of 1 A/cm(2) was boosted from 631 to 1100 V. In addition, the fabricated diode possessed a superior rectifying behavior with an ON/OFF-current ratio of 10(12), a specific differential ON-resistance of 0.75 m omega middot cm(2).
