高灵敏度的紫外光（UV）光电探测已被尝试利用非晶硒中的载流子倍增效应。在这封信中提出的原型光电探测器显示出对紫外光的极高灵敏度，因此每个入射光子产生多达1000个载流子。这一结果将导致一种高灵敏度光电探测器的开发，该光电探测器可用于覆盖可见光到紫外光区域的光谱应用。（© 2013 WILEY‐VCH Verlag GmbH & Co. KGaA，魏因海姆）
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.
