GaN/AlN Quantum Dots for Single Qubit Emitters
M. Winkelnkemper, R. Seguin, S. Rodt +2
We study theoretically the electronic properties of -plane GaN/AlN quantum dots (QDs) with focus on their potential as sources of single polarized photons for future quantum com…
Decay dynamics of neutral and charged excitonic complexes in single InAs/GaAs quantum dots
M. Feucker, R. Seguin, S. Rodt +2
Systematic time-resolved measurements on neutral and charged excitonic complexes (X, XX, X+, and XX+) of 26 different single InAs/GaAs quantum dots are reported. The ratios of the…
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…
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…
Ex-situ control of fine-structure splitting and excitonic binding energies in single InAs/GaAs quantum dots
R. Seguin, A. Schliwa, T. D. Germann +4
A systematic study of the impact of annealing on the electronic properties of single InAs/GaAs quantum dots (QDs) is presented. We are able to record single QD cathodoluminescence…
