Abstract
A novel concept and structure of a semiconductor circuit are disclosed which utilize the fact that the interaction between the carriers such as electrons and holes supplied in a meso-scopic region and the potential field formed in the meso-scopic region leads to such effects as quantum interference and resonance, with the result that the output intensity is changed.
