Theory of magneto-optical properties of neutral and charged excitons in GaAs/AlGaAs quantum dots
Diana Csontosová, Petr Klenovský
Detailed theoretical study of the magneto-optical properties of weakly confining GaAs/AlGaAs quantum dots is provided. We focus on the diamagnetic coefficient and the -factor of…
Single-Particle-Picture Breakdown in laterally weakly confining GaAs Quantum Dots
Daniel Huber, Barbara Ursula Lehner, Diana Csontosová +5
We present a detailed investigation of different excitonic states weakly confined in single GaAs/AlGaAs quantum dots obtained by the Al droplet-etching method. For our analysis we…
Optical response of (InGa)(AsSb)/GaAs quantum dots embedded in a GaP matrix
Petr Steindl, Elisa Maddalena Sala, Benito Alén +3
The optical response of (InGa)(AsSb)/GaAs quantum dots (QDs) grown on GaP (001) substrates is studied by means of excitation and temperature-dependent photoluminescence (PL), and i…
Electronic states of (InGa)(AsSb)/GaAs/GaP quantum dots
Petr Klenovský, Andrei Schliwa, Dieter Bimberg
Detailed theoretical studies of the electronic structure of (InGa)(AsSb)/GaAs/GaP quantum dots are presented. This system is unique since it exhibits concurrently direct and indire…
Effect of second order piezoelectricity on excitonic structure of stress-tuned InGaAs/GaAs quantum dots
Petr Klenovský, Petr Steindl, Johannes Aberl +4
We study the effects of the nonlinear piezoelectricity and the In distribution on the exciton energy, the electron-hole electric dipole moment, and the fine-structure splitting in…
Excitation intensity dependence of photoluminescence spectra of SiGe quantum dots grown on prepatterned Si substrates: Evidence for biexcitonic transition
P. Klenovský, M. Brehm, V. Křápek +7
The pumping intensity (I) dependence of the photoluminescence (PL) spectra of perfectly laterally two-dimensionally ordered SiGe quantum dots on Si(001) substrates was studied. The…
