Probing single charge fluctuations in a semiconductor with laser spectroscopy on a quantum dot
J. Houel, A. Kuhlmann, L. Greuter +10
We probe local charge fluctuations in a semiconductor via laser spectroscopy on a nearby self-assembled quantum dot. We demonstrate that the quantum dot is sensitive to changes in…
Laser spectroscopy of individual quantum dots charged with a single hole
B. D. Gerardot, R. J. Barbour, D. Brunner +6
We characterize the positively charged exciton (X1+) in single InGaAs quantum dots using resonant laser spectroscopy. Three samples with different dopant species (Be or C as accept…
Controlling the Interaction of Electron and Nuclear Spins in a Tunnel-Coupled Quantum Dot
C. Kloeffel, P. A. Dalgarno, B. Urbaszek +5
We present a technique for manipulating the nuclear spins and the emission polarization from a single optically active quantum dot. When the quantum dot is tunnel coupled to a Ferm…
Radiative cascade from quantum dot metastable spin-blockaded biexciton
Y. Kodriano, E. Poem, N. H. Lindner +5
We detect a novel radiative cascade from a neutral semiconductor quantum dot. The cascade initiates from a metastable biexciton state in which the holes form a spin-triplet configu…
Radiative cascades in charged quantum dots
E. Poem, Y. Kodriano, C. Tradonsky +3
We measured, for the first time, two photon radiative cascades due to sequential recombination of quantum dot confined electron hole pairs in the presence of an additional spectato…
Voltage-controlled electron-hole interaction in a single quantum dot
A. Högele, S. Seidl, M. Kroner +7
The ground state of neutral and negatively charged excitons confined to a single self-assembled InGaAs quantum dot is probed in a direct absorption experiment by high resolution la…
Photoluminescence of a single InAs quantum dot molecule under applied electric field
I. Shtrichman, C. Metzner, B. D. Gerardot +2
We study the electronic coupling between two vertically stacked InAs quantum dots, which are embedded in the center of a n-i-n structure. We use a micro-photoluminescence setup to…
