Abstract

The effect of electric field on the initial stages of copper phthalocyanine adsorption on the SiO2 substrate was studied experimentally. The external electric field was applied during thermo-vacuum evaporation of CuPc. Using atomic-force microscopy and scanning electron microscopy, it was found that in the presence of an electric field, the film morphology changes. Instead of randomly oriented elongated crystallites, new form bend-shaped ones are formed on the substrate surface. The paper provides an explanation of the experimentally observed effect of the electric field on the structure of the growing film.
