摘要
NiOx/beta-Ga(2)O(3)p-n heterojunctions fabricated on and beta-Ga2O3 substrates show distinctly anisotropic electrical properties. All three devices exhibited excellent rectification >= 10(9), and turn-on voltages >2.0 V. The device showed very different turn-on voltage, specific on-resistance, and reverse recovery time compared with and devices. Moreover, it is calculated that the interface trap state densities for and plane devices are 4.3 <bold>x</bold> 10(10), 7.4 <bold>x</bold> 10(10), and 1.6 <bold>x</bold> 10(11 )eV(-1)cm(-2), respectively. These differences in the NiOx/beta-Ga2O3 heterojunctions are attributed to the different atomic configurations, the density of dangling bonds, and interface trap state densities.
