Génération et détection optique d'ondes de spin dans les puits quantiques CdMnTe dopés n

Autor: Barate, Philippe

Ce manuscrit présente une étude sur les ondes de spin de vecteur d'onde nul par le moyen de la rotation Kerr résolue en temps. Les ondes de spin sont générées dans un puits quantique CdMnTe dopé n, ce qui introduit de la complexité dans le sy

International audience; We investigate the influence of the MgO growth process on the bias dependence of the electrical spin injection from a Co−Fe−B/MgO spin injector into a GaAs-based light-emitting diode (spin LED). With this aim, textured MgO

Optical generation and detection of spinflip waves in n doped CdMnTe quantum well

Autor: Barate, Philippe

Publikováno v: Matière Condensée [cond-mat]. Université Montpellier II-Sciences et Techniques du Languedoc, 2010. Français

During this thesis, we have used pulsating laser to generate and detect excitations inside n doped CdMnTe quantum well. The concentration in Mn in these quantum well is very low. We used the pump-probe technique to have acces to temporal domain of th
