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.
