在传统的金属-半导体-金属（MSM）光电二极管中插入绝缘层（I）可将直流光响应转换为强瞬态信号，非常适用于调制信号光电检测。在这项研究中，我们展示了有机 MISM 光电探测器的内在优势，即它们在高稳态照明下有效运行，仅响应光强度的变化，以及它们同时对多个光源做出反应的能力。此外，与由相同元件制造的复合 MSM + C 器件相比，该架构特有的 S/I 接口处的强相互作用显着增强了器件的光响应，从而实现高效的差分光电检测。 (C) 2016 年作者。除非另有说明，所有文章内容均根据知识共享署名 (CC BY) 许可证 (http://creativecommons.org/licenses/by/4.0/) 获得许可。
Inserting an insulating layer (I) into a conventional metal-semiconductor-metal (MSM) photodiode converts the DC photoresponse into a strong transient signal, highly applicable to modulated signal photodetection. In this study, we demonstrate the intrinsic benefits of organic MISM photodetectors, namely their effective operation under high steady-state lighting, responding only to changes in light intensity, and their ability to react to several light sources simultaneously. Furthermore, the strong interaction at the S/I interface, specific to this architecture, significantly enhances the device photoresponse, resulting in highly efficient differential photodetection, compared to a composite MSM + C device fabricated from identical elements.
