Rectifying contacts have been fabricated to structurally anisotropic Langmuir-Blodgett films of poly(3-hexylthiophene). The Schottky barriers were found to be of low resistance compared to the transverse resistance of the anisotropic films. The transport properties indicate bulk limited conduction and charge carrier tunnelling through thin rectifying barriers. The capacitive properties were analyzed within the framework of an appropriate equivalence circuit, and reasonable parameter values were obtained for the thin depletion layers and dopant concentrations.
