Electrical Characteristics of Pentacene Films on Cross-Linked Polymeric Insulators of Varying Thicknesses.

ABSTRACT: Pentacene films vacuum-sublimed on a cross-linked polymeric insulator (CPVP-C₆) prepared using poly(4-vinylphenol) (PVP) and 1,6-bis(trichlorosilyl)hexane (C₆) were studied with a special concern on possible influences of the CPVP-C₆ thickness on the electrical characteristics of the pentacene films. It was found that the conductivities of the pentacene films on a thin CPVP-C₆ film (10 nm) were approximately 2 orders of magnitude higher than those on a glass substrate and increased slightly with the increase in the thickness of the underlying CPVP-C₆ film. In addition, the X-ray diffraction measurements showed that the stacking structure of pentacene molecules was remarkably enhanced by increasing the thickness of the CPVP-C₆
