Аннотация:Effect of static charges on transport properties of disordered organic materials is considered. Long range nature of Coulomb interaction requires to take into consideration a finite thickness of the transport layer. Presence of conducting electrodes significantly modifies properties of organic medium, removes a long range Coulomb divergence, and makes it possible to calculate in finite form statistical properties of organic medium (with nonzero total charge density), relevant for transport characteristics. A special attention is paid to the particular case of charge induced disorder - a disorder originated from the surface charge located at the rough surface of electrodes. We present also a generalization of 1D model of charge carrier transport to the case of inhomogeneous energetic disorder that realizes in the case of charge induced disorder.
