Abstract: High-sensitivity ultraviolet (UV) photodetection has been attempted by utilizing the carrier multiplication effect in amorphous selenium. The prototype photodetector presented in this Letter showed an extremely high sensitivity to UV light, so that up to 1000 carriers are generated per incident photon. This result should lead to the development of an ultrahigh-sensitivity photodetector that can be used for spectrometric applications covering the visible to UV region. © 2013 WILEY-VCH Verlag GmbH Co.
