We investigate the embedded interfaces of GaAs/AlGaAs quantum wells grown by metal organic vapor phase epitaxy on slightly (< 1 degrees)-misoriented (001) substrates using selective etching and atomic force microscopy. Depending on the substrate misorienta ...

Quantum Dot Exciton Dynamics Probed by Photon-Correlation Spectroscopy

Elyahou Kapon, Daniel Oberli, Martin Henrik Baier

The dynamics of charging and recombination of photoexcited, site-controlled semiconductor quantum dots (QDs) are investigated using microphotoluminescence (PL) and photon-correlation spectroscopy combined with rate equation modeling. Several species of neu ...

Optimization of the efficiency of single photon sources based on quantum dots under optical excitation

Elyahou Kapon, Daniel Oberli, Martin Henrik Baier

We demonstrate efficient, regulated single-photon operation from site-controlled InGaAs quantum dots (QDs) grown on a prepatterned substrate. Under nonresonant optical excitation, carriers trapped at structural or compositional defects of the adjacent nano ...

Optical polarization anisotropy and hole states in pyramidal quantum dots

Elyahou Kapon, Daniel Oberli, Alok Rudra, Valentina Troncale

The authors present a polarization-resolved photoluminescence study of single semiconductor quantum dots (QDs) interconnected to quantum wires, measured both in a top geometry, and in a less conventional cleaved-edge geometry. Strong polarization anisotrop ...
