Abstract

Abstract Organic superlattices formed by chemical vapor deposition/molecular layer epitaxy (CVD/MLE), and a novel CVD/MLE method of forming organic molecular monolayers are disclosed. The method utilized covalent linkage, combined with layer sublimation, to form p-stacked, ordered, oriented monomolecular layers for use in a variety of electronic applications.
