Research Abstract

The control technique of carrier density in organic semiconductor single crystals by chemical doping is unestablished due to lattice mismatching. Therefore, we investigated a control technique of carrier density by charge transfer at the interface between an organic semiconductor single crystal and an organic semiconductor film. As a result, the conductivity of 1. 0 S/cm at the interface was observed.
