Abstract:

This document summarizes activities under ONR Contract N00014-86-C- 0780, under which equilibrium and nonequilibrium electron and hole transport in micron and submicron structures were studied via a wide range of numerical procedures. These included Monte Carlo methods, moments of the Boltzmann transport equation, Schrodingers equation and the quantum Liouville equation in the coordinate representation. While all of the studies have resulted in a large collection of publications, the basic theme of the studies was the determination of the physics of device operation and the influence of small structure size on this operation. The most recent activities have involved the quantum Liouville equation with emphasis on dissipation and the calculation of current. This document includes a description of quantum transport via the quantum Liouville equation, as we now understand it, as well as a brief summary of the previous activities involving larger submicron devices. While the principle goal of this study was elucidating the physics and operation of nanoscale devices, a continuing requirement was that all algorithms be menu driven and accessible to device scientists and engineers. The quantum transport algorithm is accessible on UNIX workstations and in a PC Windows format.
