Abstract

Abstract We demonstrate superb large-area vertical β-Ga2O3 SBDs with a Schottky contact area of 1 × 1 mm2 and obtain a high-efficiency DC–DC converter based on the device. The β-Ga2O3 SBD can obtain a forward current of 8 A with a forward voltage of 5 V, and has a reverse breakdown voltage of 612 V. The forward turn-on voltage (V F) and the on-resistance (R on) are 1.17 V and 0.46 Ω, respectively. The conversion efficiency of the β-Ga2O3 SBD-based DC–DC converter is 95.81%. This work indicates the great potential of Ga2O3 SBDs and relevant circuits in power electronic applications.
