The organic single-crystal field-effect transistors using anthracene derivative, H-Ant as an active layer with source/drain electrodes decorated by metal charge transfer salt(Cu TCNQ) were fabricated. We demonstrated that this bottom-contact structure displayed an obvious improvement in the electrical characteristics relative to their pristine copper and top-contact gold electrode counterparts. This observation could be ascribed to the lower contact resistance resulting from the energetic match between electrodes and semiconductor.
