CONDUCTION MECHANISMS INCLUDING TUNNELING PROCESSES IN MOLECULAR SOLIDS

Abstract

Sandwich structures using metal contacts separated by a thin film of organic solid were fabricated and the current-voltage characteristics measured. Contact materials used were Au, Cr, and Hg and the organic solids were Ca stearate and Formvar (polyvinyl formal). Currents through the film were a nonlinear function of voltage and of much greater magnitude than the bulk conductivity of the material would indicate. These characteristics indicate that quantum mechanical tunneling apparently occurs through the film. In most cases the current-voltage curve was quite symmetrical with respect to polarity but some nonsymmetry was observed when Hg was used as one contact material. (Author)
