Ultra-wide bandgap semiconductor Ga2O3 based electronic devices are expected to perform beyond wide bandgap counterparts GaN and SiC. However, the reported power figure-of-merit hardly can exceed, which is far below the projected Ga2O3 material limit. Major obstacles are high breakdown voltage ...
Deep-ultraviolet (DUV) photodetectors based on wide bandgap (WB) semiconductor materials have attracted strong interest because of their broad applications in military surveillance, fire detection and ozone hole monitoring. Monoclinic β-Ga2O3 with ultra-wide bandgap of ~4.9 eV is a promising ...
As a promising ultra-wide bandgap semiconductor, gallium oxide(Ga2O3) has attracted increasing attention in recent years. The high theoretical breakdown electrical field(8 MV/cm), ultra-wide bandgap(~ 4.8 eV) and large Baliga's figure of merit(BFOM) of Ga2O3 make it a potential candidate ...
The etching process of an ultra-wide bandgap β-Ga2O3 semiconductor is challenging, owing to its high chemical robustness and bond strength. We demonstrated the photoelectrochemical (PEC) etching of β-Ga2O3 using phosphoric acid as electrical potential and temperature were varied, both of which ...
