Résumé Les boîtes quantiques uniques présentent un grand intérêt potentiel comme brique de base des composants pour l'information quantique. Cependant, une des difficultés …
We have developed a three-dimensional model for electronic states calculation of interdiffused quantum dots (QDs) with arbitrary shape by solving the BenDaniel-Duke's …

Epitaxial self-assembled quantum dots (QDs) are commonly obtained by the Stranski- Krastanow (SK) growth mode, in which QDs form on top of a thin two-dimensional (2D) …
We have investigated the effect of strain on the g-factors of self-assembled In (Ga) As dots by single-dot spectroscopy and an eight-band effective mass calculation taking into account the …
We report a combined experimental and theoretical analysis of Sb and In segregation during the epitaxial growth of InAs self-assembled quantum dot structures covered with a GaSbAs …
We present a model for the effect of thermal annealing on a single-layer InAs/GaAs quantum dot (QD) heterostructure and study the corresponding variation in full photoluminescence …

We compare the asymmetry-induced exchange splitting δ 1 of the bright-exciton ground- state doublet in self-assembled (In, Ga) As∕ GaAs quantum dots, determined by Faraday …
