Structures de semiconducteurs II-VI à alignements de bande de type II pour le photovoltaïque

Autor: Gérard, Lionel

Ce travail porte sur l'étude d'hétérostructures de semiconducteurs II-VI à alignements de bande de type II, en particulier sous forme de superréseaux. Il s'agit d'un système qui peut être prometteur pour une application photovoltaïque, et c'e

Epitaxy of II-VI semiconductors : ZnTe/ZnSe and CdTe:Se. Study of the electronic confinement in type-II heterostructures and isoelectronic doping

Autor: Najjar, Rita

Publikováno v: Matière Condensée [cond-mat]. Université Joseph-Fourier-Grenoble I, 2008. Français

This work is based on the growth, by molecular beam epitaxy, of semiconductor heterostructures in which tellurium and selenium coexist. The goals are to develop optimized growth conditions and to study the specific physical properties due to this coe

Carrier induced ferromagnetism in (Cd,Mn)Te quantum wells: a spectroscopic study

Autor: Maslana, Wiktor

The presence of a two-dimensional hole gas in a (Cd,Mn)Te quantum well induces a ferromagnetic interaction between the localized spins of the diluted magnetic semiconductor. We have developed a new method for the doping, which uses electron traps at
