<dcterms:abstract xml:lang="fr">Dans cette thèse nous considérons un semi-conducteur de GaAs dopé, où nous étudions la relaxation du spin du côté métallique de la transition metal-isolant. Nous considérons deux types différents d'interaction de spin-orbite. Le premier d'entre eux est associé aux impuretés et l'autre est de type Dresselhaus. La dynamique du spin est traitée à travers une formulation analytique basée sur la diffusion du spin de l'électron, et un calcul numérique de la durée de vie du spin.Ensuite, nous considérons une boîte quantique hébergée dans un nanofil de matériau InAs (avec une structure cristalline de type wurtzite), afin d'étudier l'effet de l'interaction spin-orbite sur les états propres du système. Nous développons ici une solution analytique pour la boîte quantique en incluant l'interaction spin-orbite (de type Dresselhaus propre à la structure wurtzite). Nous avons calculé le facteur g effectif, ainsi que la relaxation du spin dûe aux phonons acoustiques, en utilisant les potentiels d'interaction electron-phonon propres à la structure wurtzite.</dcterms:abstract>
<dcterms:abstract xml:lang="en">In the first part of this thesis we consider a doped GaAs semiconductor and study the spin relaxation on the metallic side of the metal-insulator transition. We take into account two different types of spinorbit coupling, the first of them being associated to the presence of extrinsic impurities, while the other one is the Dresselhaus coupling. To tackle the spin dynamics problem, we develop an analytical formulation based on the spin diffusion of an electron in the metallic regime of conduction of the impurity band. The full derivation provides us with an expression for the spin-relaxation time ,which is free of adjustable parameters. We complement this approach and back our analytical results with the numerical calculation of the spin lifetime.In the second part of the thesis we consider a quantum dot hosted in an InAs nanowire (with awurtzite crystalline structure) and study the effect of spin-orbit coupling on the eigenstates of the zero-dimensional system. We develop here an exact analytical solution for the quantum dot, takinginto account the proper effective spin-orbit coupling for this type of material. We focus on the Dresselhaus coupling, which presents a cubic-in-k term, along with a linear term, characteristic of wurtzite materials. A Zeeman interaction from an external magnetic field is included as well and we compute the effective g-factor as a function of the dot size. Finally, we calculate the spin-relaxation due to acoustic phonons, taking into account the phonon potentials corresponding to the wurtzite structure.</dcterms:abstract>
