Abstract

The properties of vacuum evaporated thin films are of current interest both from applied and fundamental standpoints, as they may lead to useful and unusual devices. While such thin films have traditionally been composed of inorganic materials, it has recently been known that organic thin films can also have potentially useful electrical and optical behavior related to their large nonlinear optical susceptibilities. Thin films of large stable organic molecules such as perylenetetracarboxylic dianhydride (PTCDA) on semiconductor surfaces were extensively studied by Forrest et al. [1-4].
