Modelling the transport through organic layers on a ferroelectric substrate

Organic semiconductors, which might be suitable for logical as well as optical applications, have attracted a lot of scientific effort in recent years. This includes the understanding of the underlying transport mechanisms, the improvement of the transport characteristics and possible fields of application. The electronic transport through stacks of functionalized quaterthiophene molecules as part of a novel organic device is presented and investigated by means of a phenomenological approach called multilayer organic light-emitting diode (MOLED) [1]. Numerical results including the tuning of carrier injection and optical activity will be discussed.
