This paper shows that negative circular polarization, a spin flip of polarized carriers resulting
in emission of opposite helicity, can be observed in undoped, n-doped, and p-doped …

Highly circularly polarized light is generated from highly uniform InAs/GaAs quantum dots.
These quantum dots allowed us to observe the spin dynamics at each energy state …

Circular polarization studies of photoluminescence from the neutral (X 0) and the positively
charged (X+) excitons are reported for individual InAs/GaAs quantum dots (QDs). High …

We report optical orientation experiments performed under circularly polarized, nonresonant
excitation in n-doped quantum dot ensembles with an average number of resident electrons …

We show that circularly polarized emission light from InGaAs/GaAs quantum dot (QD)
ensembles under optical spin injection from an adjacent GaAs layer can switch its helicity …

Abstract A high degree (≈ 55%) of circular polarization has been observed for the neutral
exciton in InAs/GaAs quantum dots (QDs). The possibility to record non-zero polarization of …

We have studied the influence of an external electric field on the optical spin polarization of
initially negatively charged InAs/GaAs quantum dots (QDs). The spin polarization of the …

Spin selective optical excitation using polarizationresolved photoluminescence
spectroscopy is demonstrated in a single charge‐tunable GaAs quantum dot. The degree of …

The work is an experimental study of optical spin polarization in In As∕ Ga As quantum dots
(QDs) with two resident electrons or holes. A capture of a photogenerated electron-hole pair …

Optical pumping of electron spins and negative photoluminescence polarization are
observed when interface quantum dots in a GaAs quantum well are excited nonresonantly …
