We demonstrate the growth of InP/GaInP quantum dots on a low density InAs/GaAs island seed layer ( 10 7 cm - 2 ) by metal-organic vapor phase epitaxy. The strain produced by the underlying InAs islands results in a distinct bimodal size distribution

We perform excited-state spectroscopy of single self-assembled lateral InGaAs quantum dot molecules embedded in a planar microcavity structure, which are grown using a combination of metal-organic vapor phase and solid-source molecular beam epitaxy.

We study the electronic and optical properties of laterally coupled InGaAs/GaAs quantum dot molecules under lateral electric field. We find that electrons perceive the double-dot structure as a compound single object, while the holes discern two well

We experimentally demonstrate Cooper pairs' drastic enhancement of the band-to-band radiative recombination rate in a semiconductor. Electron Cooper pairs injected from a superconducting electrode into an active layer by the proximity effect recombin

We report on the charge carrier dynamics in single lateral quantum dot molecules and the effect of an applied electric field on the molecular states. Controllable electron tunneling manifests itself in a deviation from the typical excitonic decay beh

We demonstrate direct control over the level of lateral quantum coupling between two self-assembled InGaAs/GaAs quantum dots. This coupled system, which we also refer to as a lateral quantum dot molecule, was produced using a unique technique which c

The two laterally coupled quantum dots, also referred to as lateral quantum dot molecules, exhibit a characteristic photoluminescence spectrum consisting of six dominant emission lines that are due to neutral and charged excitonic as well as biexcito

Lateral quantum coupling between two self-assembled (In,Ga)As quantum dots has been observed. Photon statistics measurements between the various excitonic and biexcitonic transitions of these lateral quantum dot molecules display strong antibunching

We report lateral quantum coupling between two self-assembled InGaAs/GaAs quantum dots. Single-photon photoluminescence emission has been observed from this quantum dot molecule and the level of coupling can be controlled using a static electric fiel
