 This study proposes a novel approach to fabricate a two-dimensional molybdenum disulfide, MOS2, slash organic PN junction device which combines the advantages of both materials. The organic material, benzothiodiazole, BTP-4F, was used to reduce the dark current and improve the photo conductivity of the MOS2. The resulting device showed excellent performance with a fast response time of 332 microseconds and a low dark current density of 1.6 times 10 to the power of negative 8a slash cm2.
