摘要

We propose a novel structure of single-electron two-channel Multiplexer and demultiplexer based oil three coupled single-dopant quantum dots defined by enhancement gates on AlGaAs/GaAs heterostructure. Two side-gates next to the dots are designed for applying a lateral switching field to the Structure. A simple model of spherical parabolic quantum dot within effective-mass approximation demonstrates that the coupling strengths of the dots are adjustable by applying a lateral field. This gives the promise on achieving the functions of multiplexing and demultiplexing through the proposed structure. (c) 2005 Elsevier Ltd. All rights reserved.
