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.
