Charge transport in layered organic semiconductors — •Anirban Mondal and Denis Andrienko — Max Planck Institute for Polymer Research, Mainz, Germany

Modern organic electronic devices comprise of many semiconducting layers. The performance of these heterostructures is predominantly determined by the relative alignment of ionization potentials and electron affinities in each layer with respect to each other. Despite the continued scientific interest, predicting energy-level alignment at organic heterointerfaces is still a challenge in computational materials science. Using the adapted to charge systems Ewald summation technique and exploring the long-range nature of the charge-multipole interactions, we demonstrate that the density of states is a function of layer thickness and the environment in which this layer is embedded. These results contribute to the understanding of functional heterointerfaces for organic light emitting devices.
