Room-temperature single-photon emission from β-Ga₂O₃.

ABSTRACT: Single photon emitters (SPEs) hosted by the wide bandgap semiconductors have the great potential to enable quantum applications at room temperature. Recently, many defect-based SPEs have been discovered in various wide bandgap materials, such as diamond, AlN, SiC, h-BN, GaN and ZnO. Beta-phase gallium oxide (β-Ga₂O₃) is an emerging ultrawide bandgap semiconductor with promising electronic and optoelectronic properties, however, there has been no report on single-photon emission from β-Ga₂O₃ to date. Herein, we present the demonstration of room-temperature photostable single-photon emission from β-Ga₂O₃. We find that the SPEs can be found in a variety of β-Ga₂O₃ including homoepitaxial and heteroepitaxia
