Abstract: Despite a lot of studies on flexible broadband photodetectors (PDs) by employing two-dimensional (2D)-materialsbased heterostructures, their performance enhancement is limited due to the high dark current (DC) originating from the low barrier at the heterojunctions. One promising approach to reduce the DC is to locate a high-band-gap low-dimensional interfacial layer at the heterojunction interface as a blocking barrier. Here, we report the successful fabrication of an all-2D vertical heterojunction: dual-dope… Show more
