Abstract
Superconducting or conducting organic charge-transfer complex film is epitaxially grown on a substrate which has been given an oriented surface by applying a stearic acid film. The periodic charge distribution over the oriented surface regulates the formation of the complex film to arrange the molecules along a common axis. The alignment of the molecules in the complex film helps to have superconductivity or high conductivities.
