Resonant electron transfer device

A resonant electron transfer device comprising:

• a plurality of one-dimensional quantum wires each having a quantum well elongated in one direction;
• a plurality of zero-dimensional quantum dots each having a quantum well whose lowest quantum energy level is higher than that of said quantum wire of said one-dimensional quantum wire;
• and
• a plurality of electrodes formed on said quantum wires and quantum dots for controlling internal potentials of respective quantum wires and quantum dots;
• wherein said plurality of quantum wires and quantum dots are arranged alternately so as to form a predetermined connection structure;
• wherein one of said quantum wires and an adjacent one of said quantum dots are connected via a potential barrier capable of exhibiting a tunnel effect therebetween;
• and wherein information is transmitted from one of said quantum wires to one of said quantum dots or vice versa in accordance with controlling voltages supplied to said plurality of electrodes.
