Abstract

The authors reported organic phototransistors (PTs) with octadecyltrichlorosilane treated substrate based on anthrabenzothiophene. The organic PTs show a high mobility of , a maximum photoresponsivity of about 1000 A/W, and photocurrent/dark-current ratio of around 800 under white light irradiation with . The data are comparable with those of PTs based on amorphous silicon. Meanwhile, it is interesting to see that the devices show a high air-stable property and high photosensitivity via electric-field enhanced process. All these phenomena were attributed to the intrinsic optic-electronic property of the organic semiconductor and optic-electric field effect.
