Transport Simulation in Spatially Modulated Low Dimensionality Systems

摘要

The research effort addresses several issues related to nonlinear transport Inquantum wire systems characterized by spatially nonuniform confinement. We have successively investigated quantum transport through a variety of quantum cavities by using a Recursive Green Function Technique with emphasis on the effect of disorder on the conductance of the structure, one-dimensional transport in coupled quantum boxes structures with emphasis on the effect of suppression of optic phonon scattering on the transport properties, and finally the detailed influence of confined optic phonon modes on the scattering processes in quantum wires.
