We present a theoretical study of Ge-core/Si-shell nanocrystals in a wide bandgap matrix and compare the results with experimental data obtained from the samples prepared by co-sputtering. The empirical tight-binding technique allows us to account fo

We propose an engineering of the optical properties of GaAs/AlGaAs quantum wells using AlAs and InAs monolayer insertions. A quantitative study of the effects of the monolayer position and the well thickness on the interband and intersubband transiti

Entangled photon pairs are essential components for practical quantum information applications. Two different approaches for producing entanglement are available: parametric conversion in a nonlinear optical medium, or radiative decay of electron–h

We study two charging mechanisms of CdTe self assembled quantum dots embedded in a field effect structure: A standard electrical injection of carriers from the back contact resulting from an application of a gate voltage and a novel all-optical effec

A selection of optical experiments is presented, demonstrating the utility of semiconductors in two novel areas of research: spintronics and quantum information. First we show examples of spin manipulation in semiconductor quantum wells. The light is

International audience; A procedure to obtain single-electron wave functions within the tight-binding formalism is proposed. It is based on linear combinations of Slater-type orbitals whose screening coefficients are extracted from the optical matrix

Entangling a single spin to the polarization of a single incoming photon, generated by an external source, would open new paradigms in quantum optics: this relies on the possibility that a single spin induces a macroscopic rotation of a photon polari

We report on electron spin physics in a single charge-tunable self-assembled InAs/GaAs quantum dot. The hyperfine interaction between the optically oriented electron and nuclear spins leads to the polarization of the quantum dot nuclei. The sign of t

We present results of polarization-resolved micro-photoluminescence (μ-PL) experiments on self-organized InAs/GaAs (QDs). We have investigated how Coulomb interactions are modified by application of an electric field. We observed systematic variatio
