[Influences of transport layers barriers on recombination efficiency in bilayer organic devices].

Based on the physical processes of carriers transport and recombination, a multi-barriers model for carriers transport and recombination in bilayer organic devices is present. The influences of applied bias and thin films (transport layers) barriers on carriers recombination and its efficiency are calculated and discussed. In bilayer organic devices the charge density inside the sample is controlled by interfacial charge accuulation.
