Polarized Emission Lines from Single InGaN/GaN Quantum Dots: Role of the Valence-band Structure of Wurtzite Group-III Nitrides
M. Winkelnkemper, R. Seguin, S. Rodt +5
We present a study of the polarization properties of emission lines from single InGaN/GaN quantum dots (QDs). The QDs, formed by spinodal decomposition within ultra-thin InGaN quan…
Polarized emission lines from A- and B-type excitonic complexes in single InGaN/GaN quantum dots
M. Winkelnkemper, R. Seguin, S. Rodt +5
Cathodoluminescence measurements on single InGaN/GaN quantum dots (QDs) are reported. Complex spectra with up to five emission lines per QD are observed. The lines are polarized al…
Controlling surface morphologies by time-delayed feedback
M. Block, B. Schmittmann, E. Schoell
We propose a new method to control the roughness of a growing surface, via a time-delayed feedback scheme. As an illustration, we apply this method to the Kardar-Parisi-Zhang equat…
Control of fine-structure splitting and excitonic binding energies in selected individual InAs/GaAs quantum dots
R. Seguin, A. Schliwa, T. D. Germann +8
A systematic study of the impact of annealing on the electronic properties of single InAs/GaAs quantum dots (QDs) is presented. Single QD cathodoluminescence spectra are recorded t…
