ORGANIC TRANSISTOR AND DEVICE FOR CONTROLLING OPERATIONS OF ORGANIC TRANSISTOR

To provide an organic transistor which can materialize various operations by itself, and a device for controlling operations of such an organic transistor.SOLUTION: The organic transistor of the present invention has a photoisomerizing molecule film as a semiconductor film for channel formation. The organic transistor comprises a plurality of electrodes formed on the photoisomerizing molecule film so that they are apart from each other. In the photoisomerizing molecule film, photoisomerizing molecules which form the photoisomerizing molecule film each have a closing ring structure in a channel region and an opening ring structure in the other regions. The channel region serves to connect between the electrodes. The organic transistor further comprises an insulator layer located on one surface of the photoisomerizing molecule film and a resin layer located between the photoisomerizing molecule film and the insulator layer. The resin layer is in contact with the insulator layer in a part which overlaps with the channel region between the electrodes in plan view.SELECTED DRAWING: Figure 1 【課題】単体で、多彩な動作を実現することが可能な有機トランジスタ及び有機トランジスタの動作制御装置を提供する。【解決手段】本発明の有機トランジスタは、光異性化分子膜をチャネル形成用の半導体膜として備えた有機トランジスタであって、前記光異性化分子膜上に互いに離間して形成された複数の電極を備え、前記光異性化分子膜を構成する光異性化分子が、前記光異性化分子膜のうち、チャネル領域においては閉環体構造を有し、他の領域においては開環体の構造を有しており、前記チャネル領域が、前記電極間を連結しており、前記光異性化分子膜の一面側に位置する絶縁層と、前記光異性化分子膜と前記絶縁層との間に位置する樹脂層と、をさらに備え、前記樹脂層は、平面視で前記電極間のチャネル領域と重なる部分において、前記絶縁層と接している。【選択図】図１
