Abstract

Electronic devices, such as organic thin film transistors, with improved mobility are disclosed. The semiconducting layer comprises layers or striations of an organic semiconductor and graphene, including alternating layers/striations of such materials. The organic semiconductor and graphene layers interact well together because both materials form lamellar sheets. The presence of graphene enhances mobility by correcting molecular packing defects in the organic semiconductor layers, and the conductivity of graphene can be controlled. Finally, both materials are flexible, allowing for flexible semiconductor layers and transistors.
