Abstract
A switching device is provided which comprises a pair of electrodes, and a insulating zone and a conductive or semiconductive zone that are provided between said electrodes. Another switching device is also provided which comprises a pair of electrodes, and a laminated structural body in which an insulating thin film and a conductive or semiconductive thin film are alternately laminated between said electrodes in the direction vertical to the surfaces of said electrodes. This device may be used for a switching process in which an electric circuit is switched from the switched off state to the switched-on state by irradiation of electromagnetic radiation.
