摘要: Etude analytique et numerique de la localisation d'Anderson dans les systemes lesquels le caractere aleatoire est anisotrope intermediaire entre differentes dimensions. En fonction du parametre d'anisotropie θ, qui s'intercalle un systeme en couches unidimensionnel isotrope tridimensionnel, resultats montrent l'existence d'un θc critique dependant l'energie Fermi dessous duquel d'onde localisee pour arbitrairement petit. Observation phenomene reentree interessant diagramme phases au voisinage bord bande, ou densite d'etats faible. Obtention des expressions analytiques longueurs regime localise lors que petit
