Electric field induced tuning of electronic correlation in weakly confining quantum dots
Huiying Huang, Diana Csontosová, Santanu Manna +4
We conduct a combined experimental and theoretical study of the quantum-confined Stark effect in GaAs/AlGaAs quantum dots obtained with the local droplet etching method. In the exp…
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…
Inversion of the exciton built-in dipole moment in In(Ga)As quantum dots via nonlinear piezoelectric effect
Johannes Aberl, Petr Klenovský, Johannes S. Wildmann +6
We show that anisotropic biaxial stress can be used to tune the built-in dipole moment of excitons confined in In(Ga)As quantum dots up to complete erasure of its magnitude and inv…
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…
