ABSTRACT:
This invention provides an electrically plastic device in which an electron conjugated polymeric semiconductor layer containing a mobile dopant is formed across a pair of electrodes and at least one gate electrode is provided between said pair of electrodes with an insulating layer or a high-resistance layer interposed along said electron conjugated polymeric semiconductor layer, so that the dopant distribution in said electron conjugate polymeric semiconductor layer is controlled through said gate electrode, thereby controlling the electrical conductivity of said electron conjugated polymeric semiconductor layer. The device utilizes the substantially large variation in the electrical conductivity of an electrically conductive polymer depending on its dopant concentration, thus allowing a high-gain neurochip to be constructed. The control method of the electrically plastic device in accordance with this invention is carried out in such a way that a positive or negative pulse voltage is applied to the gate electrode to control the dopant distribution in the electron conjugated polymeric semiconductor layer, thereby varying the conductivity thereof, which is used as a learning or reset operation so as to make said gate electrode at ground potential so that the pair of electrodes (source and drain) are driven into conduction.
