Abstract
Abstract An organic thin film element has a structure in which an organic thin film layer, an insulating layer, and a back electrode are sequentially formed on a substrate obtained by forming an electrode, an insulating layer and a layer consisting of polycyclic aromatic group molecules or a derivative thereof or a carbon layer having a graphite structure on the surface of a substrate main body. An effect of controlling the orientation of the organic thin film layer can be enhanced by the surface layer of the substrate similar in chemical structure to molecules constituting the organic thin film layer. A neutral-ionic transition of a complex can be effectively caused by an electric field applied from the electrodes.
