Title: How Much Will Gallium Oxide Power Electronics Cost?

Abstract

Power electronics are used to convert between different forms of electrical energy, representing an enormous technological and financial growth opportunity. SiC semiconductor has wider bandgap and offer higher energy conversion efficiencies than Si, but at higher cost. Here, we show by modeling that the wafer cost of an emerging Ga2O3 wide bandgap semiconductor can be >3x lower compared to SiC. This lower cost of the Ga2O3 wafers should lead to less expensive high-performance power electronic devices in the future.
