Abstract
A quantum box structure and a carrier conductivity modulating quantum device are disclosed. The quantum box structure comprises a quantum boxes array including a plurality of quantum boxes arranged adjacent to each other on a common plane. Each quantum box is asymmetric in a direction orthogonal to the plane in one of composition of materials constituting the quantum box and geometry of the quantum box. The carrier conductivity modulating quantum device comprises a plurality of regions including quantum boxes arrays including a plurality of quantum boxes arranged on a common plane. Each regions exhibits at least one of a metal phase and an insulator phase. Each quantum box is asymmetric in a direction orthogonal to the plane at least in one of composition of materials constituting the quantum box and geometry of the quantum box.
