Solid-State Dynamics and Quantum Transport in Novel Semiconductor Nanostructures
Abstract
The objective of this research program is to study theoretically the underlying principles of solid-state dynamics and quantum mechanical transport of carriers in ultrasmall novel semiconductor devices. The areas of research are: (1) theory of phonon modes in reduced dimensions, (2) effects of band structure on electronic and optical properties of heterostructures, and (3) quantum transport in solids with special emphasis on non-perturbative role of high-electric fields and many-body effects in dynamical processes. The treatment of these problems is mainly analytical through the development of macroscopic and microscopic physical models with an emphasis on quantum mechanical principles. At the same time, numerical approaches has also been utilized for realistic solutions with accuracy. Specific subjects discussed in this report include the effects of confinement and localization on optical phonon modes, band mixing in tunneling, Bloch electron quantum transport theory under hot- electron conditions, and dielectric response function theory.
