CdS/CdSe/CdS spherical quantum wells as single-photon sources
A. Allemand, F. Kulzer, B. Mahler +2
We have synthesized CdS(1.3 nm)/CdSe(1.7 nm)/CdS(3.4 nm) spherical quantum wells with 13 nm diameter and demonstrated the first antibunching of their emission, labelling them as si…
Doping MAPbBr hybrid perovskites with CdSe/CdZnS quantum dots: from emissive thin-films to hybrid single-photon sources
Justine Baronnier, Julien Houel, Christophe Dujardin +2
We report the first doping of crystalline methylammonium lead bromide (MAPbBr) perovskite thin-films with CdSe/CdZnS core/shell quantum dots (QDs), using a soft-chemistry metho…
Optical Properties of Fully Inorganic, Spacer-Free Core/Gradient-Shell CdSe/CdZnS Nanocrystals at the Ensemble and Single-Nanocrystal Levels
Justine Baronnier, Benoit Mahler, Christophe Dujardin +2
We report the synthesis and optical characterization of fully inorganic gradientshell CdSe/CdZnS nanocrystals (NCs) with high luminescence quantum yield (QY, 50 percent), which wer…
Electrically-tunable hole g-factor of an optically-active quantum dot for fast spin rotations
Jonathan H. Prechtel, Franziska Maier, Julien Houel +5
We report a large g-factor tunability of a single hole spin in an InGaAs quantum dot via an electric field. The magnetic field lies in the in-plane direction x, the direction requi…
Autocorrelation analysis for the unbiased determination of power-law exponents in single-quantum-dot blinking
J. Houel, Q. T. Doan, T. Cajgfinger +11
We present an unbiased and robust analysis method for power-law blinking statistics in the photoluminescence of single nano-emitters, allowing us to extract both the bright- and da…
High resolution coherent population trapping on a single hole spin in a semiconductor
Julien Houel, Jonathan H. Prechtel, Daniel Brunner +5
We report high resolution coherent population trapping on a single hole spin in a semiconductor quantum dot. The absorption dip signifying the formation of a dark state exhibits an…
A frequency-stabilized source of single photons from a solid-state qubit
Jonathan H. Prechtel, Andreas V. Kuhlmann, Julien Houel +5
Single quantum dots are solid-state emitters which mimic two-level atoms but with a highly enhanced spontaneous emission rate. A single quantum dot is the basis for a potentially e…
Transform-limited single photons from a single quantum dot
Andreas V. Kuhlmann, Jonathan H. Prechtel, Julien Houel +4
A semiconductor quantum dot mimics a two-level atom. Performance as a single photon source is limited by decoherence and dephasing of the optical transition. Even with high quality…
A dark-field microscope for background-free detection of resonance fluorescence from single semiconductor quantum dots operating in a set-and-forget mode
Andreas V. Kuhlmann, Julien Houel, Daniel Brunner +4
Optically active quantum dots, for instance self-assembled InGaAs quantum dots, are potentially excellent single photon sources. The fidelity of the single photons is much improved…
