Recent progress on the effects of impurities and defects on the properties of Ga2O3

Herein, the effects of impurities ( e.g. , donors, acceptors, co-doping impurities, Al and In, and surface passivators) and defects ( e.g. , intrinsic defects and deep-level defects) on the material properties of Ga 2 O 3 are summarized.
