This dissertation describes
two approaches to the numerical modelling of electroluminescence in
nanostructured semiconductor light-emitting diodes (LEDs). The semiclassical
simulator tdkp/AQUA aims at the unified description of transport and luminescence
in three-dimensional structures with varying degrees of quantization. As
examples serve an AlGaAs-based quantum wire LED and an InGaN-based nanocolumn
LED. The second simulator employs the NEGF formalism for a fully
quantum-mechanical description of planar nanostructures, enabling deep physical
insight into scattering, carrier capture and energetic carrier distributions. A
GaAs resistor and an AlGaAs-based quantum well LED are investigated.
About the Author
Sebastian Steiger was born in 1981 and grew up in Thalwil, Switzerland. He finished his
studies in physics at the Swiss Federal Institute of Technology Zurich (ETHZ)
in 2005 with a diploma thesis on single quantum dot spectroscopy. From 2005 to
2009 he was a research and teaching assistant at the Integrated Systems Laboratory
(IIS), ETHZ. His research interests lie in the field of semiconductor physics,
in particular the modelling of classical and quantum-mechanical transport
through nanostructures, interactions between electrons, holes, phonons and
photons, and light emission spectra. In his spare time, he enjoys playing the
saxophone.
