Abstract
A quantization functional device includes: a silicon thin layer having a first surface and a second surface each made of a predetermined crystal surface, and the silicon thin layer being formed of single crystalline silicon having a thickness sufficiently thin to function as a quantum well; a pair of tunnel barriers respectively provided on the first and second surfaces of the silicon thin layer; and a first electrode and a second electrode operatively coupled to each other and formed so as to interpose the silicon thin layer and the pair of the tunnel barriers therebetween.
