Abstract

Oriented diode-like molecules in a polymer binder are the new approach described here for overcoming the problems associated with Schottky and p-n junctions in semiconductor devices. The principles relies on the intrinsic polar nature of the organic molecules used–which causes them to orient in an applied static electric field–and is expected to improve significantly the efficiency of polymeric semiconductor devices. The principle is outlined and experimental evidence presented for molecular rectification equivalent to ad distributed p-n homojunction.
