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.
