▎ 摘  要

We describe the observation of photoconductivity and enhanced memory effects in graphene devices functionalized with clusters of alkylated C-60 molecules. The alkylated C60 clusters were adsorbed on chemical vapor deposition-grown graphene devices from an aprotic medium. The resulting alkylated C-60-graphene hybrid devices showed reproducible photoconductive behavior originating from the electron-accepting nature of the C-60 molecules. Significantly enhanced gate hysteresis was observed upon illumination with visible light, thereby enabling the use of C-60-graphene hybrid devices in three-terminal photo-memory applications.
