Abstract
Abstract A semiconductor data transmission device having an MIS structure including an intrinsic semiconductor and a plurality of metallic electrodes disposed in a predetermined pattern on its insulating layer. One of the electrodes serves as a gate electrode for injecting both groups of positive polarity carriers and groups of negative polarity carriers successively into the semiconductor and the remaining electrodes are interconnected by a time delay line. A pulse is applied to one end of the time delay line connected to that electrode nearest to the gate electrode to simultaneously transfer those groups of positive carriers and those groups of negative carriers injected into the semiconductor. A low frequency voltage is supplied to a particular one of the electrode to form carriers opposite in polarity from the moved carriers below it to extinguish the latter through the recombination.
