Analysis of electron waveguides
Abstract
This thesis presents a study of ballistic electron transport in semiconductor electron waveguides using the Landauer approach. An introduction is provided in Chapter I. Chapter II contains a method of modeling electron transfer across an abrupt junction where the confining potentials may differ widely. Chapter III contains an application of this method to the Aharonov-Bohm device with wide contacts; it is shown that negative correlation exists between the interference of modes with opposite parity in the contacts. Chapter IV describes a method for calculating the conductance of any semiconductor waveguide structure at a computational cost proportional to L$\sp2$, and is the most significant work in this thesis.
