Beta gallium oxide (ß-Ga2O3) is a promising wide bandgap semiconductor crystal. Its wide bandgap of 4.8 - 4.9 eV, high breakdown field of 8 MV/cm, high dielectric constant  and good electron mobilities can be translated into a high voltage Baliga figure of merit (HV-BFOM) that is > 3000 times greater than that of Si, > 8 times greater than that of 4H-SiC, and > 4 times that of GaN. In addition, its high frequency Baliga figure of merit is ~150 times that of Si, ~3 times that of 4H-SiC, and 50% greater than that of GaN.
