[PROBLEMS] To provide a technique achieving a performance surpassing the current CMOS technology from the viewpoint of microfabrication and power consumption, and capable of realizing a logic circuit of a system not contradictory to mounting a classic computer employing an existing sequential circuit. [MEANS FOR SOLVING PROBLEMS] A quantum device comprises first conductive members(101a and 101b) and second conductive members (102a and 102b) confining carriers in the z direction and having two dimensional electron gas on the xy plane, third conductive members(103a and 103b) generating an electric field having an effect on the first conductive members(101a ,101b), an insulating member (104) easily passing a tunnel current between the first conductive members (101a, 101b) and the second conductive members (102a, 102b), and an insulating member(105) hardly passing a tunnel current between the first conductive members (101a, 101b) and the third conductive members (103a, 103b). An electric field generated by a potential applied to the third conductive members (103a, 103b) has an effect on the sub-band of the first conductive members(101a, 101b). |
