Abstract: A field effect device includes a source electrode, a drain electrode, a channel formed between the source electrode and the drain electrode, and a gate electrode formed directly on the channel and arranged in a gap between the source electrode and the drain electrode. The channel includes a switching material that is reversibly switchable between a lower conductivity state and a higher conductivity state. The first conductivity state has an electrical conductivity which is lower than an electrical conductivity of the second conductivity state. Each of the conductivity states is persistent without the need for a sustaining excitation signal including an electrical field, heat and/or light applied to the device.

Abstract: A method for manufacturing an organic electronic device including a stack of layers with a lateral structure on a substrate, at least one of the layers being an organic material layer. A method includes with the step of providing a stamp with at least one protrusion of the surface area corresponding to the lateral structure.
