MOCVD epitaxy and doping for beta-Ga2O3 and (AlxGa1-x)2O3 (Conference Presentation)
Author(s): Hongping Zhao

Paper Abstract

β-Ga2O3 represents the emerging ultrawide bandgap semiconductor material, having a bandgap of 4.5-4.9 eV and estimated breakdown field of 6-8 MV/cm, promising for power electronic devices and solar blind photodetectors. High quality material growth and fundamental understanding of its ternary alloy (AlxGa1-x)2O3 are still lacking. Metalorganic chemical vapor deposition (MOCVD) growth of β-Ga2O3 and (AlxGa1-x)2O3 are studied with the focus on understanding the effects of growth conditions on the material quality, control of background and n-type doping, as well as transport properties. Record high room temperature and low temperature mobilities have been achieved in MOCVD β-Ga2O3.
