Light-modulated graphene-organic heterojunction transistors realizing photocurrent logic changes

(Light Publishing Center, Changchun Institute of Optics, Fine Mechanics And Physics, CAS) The optical intermodulation and graphene removing doping modulation proposed in this paper provide a reference for the future fabrication of graphene-based all-optical input photodetectors and photoelectric modulation devices, as well as positive and negative logic photocurrents modulated by utilizing critical value of effective exciton length. This logical reversal light modulation photoresponse opens up a...
