【International Papers】Consistent reporting of performances in Ga₂O₃ UV-C photodetectors

      Researchers from the University of Strathclyde have published a dissertation titled "Consistent reporting of performances in Ga₂O₃ UV-C photodetectors" in APL Electronic Devices.

Abstract

      The study addresses the lack of consistency with reporting of Ga₂O₃ photodetector performances and assesses the impact of illumination intensity, illumination wavelength, and voltage bias on photodetector responsivity and time response. The approach reveals the electronic processes at play during Ga₂O₃ photodetector operation and provides qualitative insights into the defect spectroscopy of the materials. More importantly, the study highlights that high performance claims could be engineered through selective use of testing conditions and warns of malpractices when reporting performances, which could result in misleading comparisons. Finally, the study makes recommendations for future works reporting photodetector performances to enable normalization of performances, allowing fair comparisons across the literature. These recommendations are not specific to Ga₂O₃ and can be applied to other semiconductors.
