A comparison of atomistic and continuum theoretical approaches to determine electronic properties of GaN/AlN quantum dots
Oliver Marquardt, Daniel Mourad, Stefan Schulz +3
In this work we present a comparison of multiband k.p-models, the effective bond-orbital approach, and an empirical tight-binding model to calculate the electronic structure for th…

Spin-orbit coupling and crystal-field splitting in the electronic and optical properties of nitride quantum dots with a wurtzite crystal structure
S. Schulz, S. Schumacher, G. Czycholl
We present an tight-binding model for the calculation of the electronic and optical properties of wurtzite semiconductor quantum dots (QDs). The tight-binding model takes in…

Weak-coupling Treatment of Electronic (Anti-)Ferroelectricity in the Extended Falicov-Kimball Model
Claudia Schneider, Gerd Czycholl
We study the (spinless) Falicov-Kimball model extended by a finite band width (hopping ) of the localized (f-) electrons in infinite dimensions in the weak-coupling limit of a…
