Cette thèse présente des mesures de transport électronique dans des systèmes bi-dimensionels et uni-dimensionels à base de graphène sous champ magnétique pulsé (60T). L'objectif de ces travaux consiste à sonder la dynamique des porteurs de charge en modifiant la densité d'états du système par l'application d'un champ magnétique. Une première partie est consacrée à l'étude de l'influence des îlots électrons-trous sur les propriétés de transport du graphène au voisinage du point de neutralité de charge. Nous avons constaté l'apparition de fluctuations de la magnéto-résistance liée à la transition progressive des îlots de taille finie dans le régime quantique lorsque le champ magnétique augmente. Nous avons aussi montré que la variation de l'é...
