Unraveling Abnormal Thermal Quenching of Sub‐Gap Emission in β‐Ga2O3

Abstract In this work, the optical transition of self‐trapped excitons (STEs) and the emergent green emission in β‐Ga2O3 samples with/without Sn impurities at various doping levels have been investigated via temperature‐ and power‐dependent photoluminescence. The ultraviolet (UV) emissions ≈ 3.40 eV...
