In this paper, we report on achieving the first high performance lateral beta-Ga2O3 Schottky barrier diode (SBD) on sapphire substrate via transferring beta-Ga2O3 nano-membrane channel from a low dislocation density bulk beta-Ga2O3 substrate. Non field-plated lateral SBDs with Schottky-Ohmic contact distance of 4, 6, 11, and 15 mu m demonstrate a reverse breakdown voltage (BV) of 0.64, 0.85, 1.2, and 1.7 kV with on resistance (R-on) of 47, 66, 91, and 190 Omega center dot mm, respectively. This lateral R-on,(Sp) similar to BV performance is comparable to that of vertical SBDs. Combining with 10(7) similar to 10(8) high temperature current on/off ratio, beta-Ga2O3 SBD shows its great promise for power rectifying once the beta-Ga2O3 drift layer epitaxial growth becomes more mature.
