A novel organic/graphene/inorganic heterostructure , consisting of a graphene layer encapsulated by n‐ and p‐type photoactive materials with complementary absorptions, enables the control of dual n‐ and p‐typed transport behaviors of a graphene transistor under selective UV or visible light illumination. A graphene‐based p‐n junction created by spatially patterned wavelength‐selective illumination using the organic/graphene/inorganic heterostructure is also demonstrated.
