Effects of variable anisotropic-strain on the emission of neutral excitons confined in epitaxial quantum dots
J. D. Plumhof, V. Krapek, F. Ding +8
We study the effect of elastic anisotropic biaxial strain on the light emitted by neutral excitons confined in different kinds of semiconductor quantum dots (QDs). We find that the…
Polarization anisotropy of the emission from type-II quantum dots
P. Klenovsky, D. Hemzal, P. Steindl +3
We study the polarization response of the emission from type-II GaAsSb capped InAs quantum dots. The theoretical prediction based on the calculations of the overlap integrals of th…
Type-II InAs/GaAsSb/GaAs quantum dots as artificial quantum dot molecules
P. Klenovsky, V. Krapek, J. Humlicek
We have studied theoretically the type-II GaAsSb capped InAs quantum dots for two structures differing in the composition of the capping layer, being either (i) constant or (ii) wi…
LDA+DMFT approach to ordering phenomena and the structural stability of correlated materials
J. Kunes, I. Leonov, P. Augustinsky +3
Materials with correlated electrons often respond very strongly to external or internal influences, leading to instabilities and states of matter with broken symmetry. This behavio…
Doping Induced Spin State Transition in LaCoO3: Dynamical Mean-Field Study
P. Augustinsky, V. Krapek, J. Kunes
Hole and electron doped LaCoO3 is studied using dynamical mean-field theory. The one-particle spectra are analyzed and compared to the available experimental data, in particular th…
