Abstract

We have theoretically investigated the coherent transport in quantum-mechanically coupled quantum wire structures by using the tight-binding Green's function method. Extension of the method to a four-terminal geometry is found to be essential in predicting transmission characteristics of quantum-wire electron wave directional coupling structures. It is found that the interwire transmission probability can be tuned from 0.02 to 0.95 by applying external gate electric fields. Thus, we have confirmed the basic operation of field-effect switching action. Furthermore, we have investigated the effect of a potential gradient along the channel on the transmission coefficients and found that the potential gradient significantly improves the interwire transmission probabilities.
