A differential photodetector: Detecting light modulations using transient photocurrents

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, na...
