Abstract
A charge transfer device comprises a quantum wire and a one-dimensional quantum dots array extending helically, for example, and including quantum dots which are aligned in close relation to couple with each other and to surround the quantum wire. By applying an external field within a plane normal to the quantum wire and by rotating the direction of the application of the external field, charges are transferred along the quantum wire.
