Les défauts ponctuels dans les matériaux à grande bande interdite font l’objet de nombreuses recherches, compte tenu des perspectives d’applications en technologie quantique. La réalisation de qubits et de capteurs quantiques a échelle nanomètres à l’aide du centre NV– a suscité la recherche de défauts ayant des propriétés magnéto-optiques similaires, mais dans un matériau technologiquement plus mûr tel que le carbure de silicium (SiC). Le SiC se présente sous différentes structures cristallographiques, notamment cubique (3C) et hexagonales (4H et 6H). Cette propriété permet d’obtenir une plus grande variété de défauts ponctuels profonds. Dans cette thèse, j'ai établi présence du défaut azote-lacune (NCVSi) de spin S=1 dans un échantillon d...
