Abstract:

This dissertation deals with parts
of the theory and its numerical implementation of a novel simulator
\emph{tdkp/AQUA}, suitable for the unified simulation of nanostructures for
optoelectronics of any dimensionality. Here, the calculation of realistic
electronic band structure, including strain and polarization effects, and the
optical properties of nanostructures are covered. The presented theory is based
on a continuum formulation of the physical behavior of the involved
semiconductor crystal. As a central novelty, the **k*p** envelope function method for the band structure calculation is
formulated absolutely spurious solution free by ensuring a mathematical
consistent formulation retaining the elliptical nature of the equation. The
optical properties are calculated within a density matrix formalism. Many-body
effects due to Coulomb interactions between charge carriers are included on the
level of the screened Hartree-Fock theory. At the end, an analysis of
GaN-nanocolumn LEDs using the developed simulator is presented.

About the Author

Ratko G. Veprek was born in Zurich, Switzerland, in 1978. After
studies in physics from 1998 to 2001, he followed the Computational Science and
Engineering (CSE) curriculum at the ETH
Zurich (Switzerland) from 2001 to 2004, graduating as Dipl. Rech. Wiss. ETH in October 2004. He joined the
Integrated Systems Laboratory at the ETH
Zurich in August 2005 as a research and teaching assistant in the
Computational Optoelectronics Group. His research interests comprise the
interdisciplinary approach to the computational modeling of physical processes.
