Abstract

Light-emitting devices made by organic or inorganic dielectric films placed between two metal electrodes emit light because of the radiative recombination of positive and negative charge carriers entering the dielectric from the anode and cathode sides, respectively, under applied voltage. Standard vapor-deposition technology of the device construction suggests the remarkable disordering at the metal dielectric interface and in the structure of dielectric film. The structural imperfections strongly affect carrier injection and transport, device efficiency, performance, and stability. In this article we describe the effect of disordering on the injection current through the dielectric layer and discuss the implications for the device performance.
