In the past decade, a two-dimensional matter-light system called the microcavity exciton-
polariton has emerged as a new promising candidate of Bose-Einstein condensation (BEC) …

We have studied the electron spin relaxation in semiconductor InAs/GaAs quantum dots by
time-resolved optical spectroscopy. The average spin polarization of the electrons in an …

Using the trion as a monitor we investigate the anisotropy of the single-hole state in epitaxial
Cd Se∕ Zn Se quantum dots. Heavy-light hole mixing caused by a symmetry reduction …

We report polarized photoluminescence excitation spectroscopy of the negative trion in
single charge-tunable InAs/GaAs quantum dots. The spectrum exhibits ap-shell resonance …

We present a detailed investigation of different excitonic states weakly confined in single
GaAs/AlGaAs quantum dots obtained by the Al droplet-etching method. For our analysis we …

The fine structure of the “excited-electron” trion triplet state in negatively charged Cd Se∕ Zn
Se self-assembled quantum dots is studied using polarization-selective as well as magneto …

Light-induced orientation of electron spins in the negatively charged InP quantum dots is
found to persist longer than 100 μ s. We have proved experimentally that the long-lived …

The fundamental building block of quantum information processing technologies is the
quantum-bit a'qubit.'These technologies require the ability to prepare, control, and read out a …

We present a comprehensive study of the optical transitions and selection rules of variably
charged single self-assembled InAs/GaAs quantum dots. We apply high resolution …

We present a detailed investigation into the optical characteristics of individual InAs
quantum dots (QDs) grown by metalorganic chemical vapor deposition, with low …
