Investigations of the Optical and Electronic Properties of Crystalline Organic Semiconductors.

Abstract

During the course of this program, major advances have been made in our understanding of the growth and optical properties of organic nanostructures. For example, we have found that a clear indication of quasi-epitaxial growth of an organic molecule is failure of the epitaxial layer to reduce strain by the generation of defects as films thickness is increased. Furthermore, studies of the optical spectra of closely packed molecules such as PTCDA indicate that organic nanostructures (such as multiple quantum wells) can be used to change the electronic and optical properties of organic materials in much the same manner as in inorganic semiconductors. Further, we have demonstrated high efficiency organic light emitting devices, as well as the invented the process of organic vapor phase deposition (OVPD) for achieving ordered growth of organic salts for nonlinear optics applications.
