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…
Measurement of the spin temperature of optically cooled nuclei and GaAs hyperfine constants in GaAs/AlGaAs quantum dots
E. A. Chekhovich, A. Ulhaq, E. Zallo +3
Deep cooling of electron and nuclear spins is equivalent to achieving polarization degrees close to 100% and is a key requirement in solid state quantum information technologies. W…
Electrically-Pumped Wavelength-Tunable GaAs Quantum Dots Interfaced with Rubidium Atoms
Huiying Huang, Rinaldo Trotta, Yongheng Huo +9
We demonstrate the first wavelength-tunable electrically-pumped source of non-classical light that can emit photons with wavelength in resonance with the D2 transitions of 87Rb ato…
Scalable Sources of Entangled Photons with Wavelength on Demand
Rinaldo Trotta, Javier Martin-Sanchez, Johannes S. Wildmann +8
The prospect of using the quantum nature of light for secure communication keeps spurring the search and investigation of suitable sources of entangled-photons. Semiconductor quant…
Electron and nuclear spin properties of the nanohole-filled GaAs/AlGaAs quantum dots
Ata Ulhaq, Qingqing Duan, Fei Ding +5
GaAs/AlGaAs quantum dots grown by in-situ droplet etching and nanohole infilling offer a combination of strong charge confinement, optical efficiency, and spatial symmetry required…
