Optical and Transport Properties of One-Dimensional Quantum Wire Structures

摘要

We calculate optical and transport properties of semiconductor quantum wirestructures and compare our theoretical results with available experimental data. Optical properties are calculated by developing a theory for the far-infrared electromagnetic response of the system in the multi-subband occupancy situation, including effects of both intrasubband and inter-subband excitations and the mode-coupling between them. Transport properties are calculated for the currently experimentally interesting quantum constriction structures from the ballistic to the diffusive regime by using the recursive Green's function technique. Good agreement between our theory and experiment is found for both optical and transport properties.
