Abstract
In this work a specific quantum interference device, which is two coupled-electron waveguides in close proximity, is described and analyzed. After an initial analysis outlining the principle of operation and the constraints on the structure dimensions and material parameters, a specific structure is simulated using a self-consistent Poisson and Schrödinger solver. Results indicate that this device is feasible using current fabrication technology.This publication has 7 references indexed in Scilit:
