Graphene band engineering by single atomic layer intercalation

Abstract : Nowadays graphene based systems have no particular use in spintronic or magnetic information storage applications mainly due to the lack of magnetic moments in the carbon and the negligible electron spin interaction with the electron motion (spin-orbit coupling). This situation changes dramatically when graphene is interfaced with other materials. Spin-orbit coupling can be induced in graphene by its interactions with heavy metals (HM) and carbon atoms can acquire magnetic moment when interfaced with ferromagnetic elements (FM). This project aims to the fabrication and the characterization of the first highly crystalline graphene/HM/FM hybrid system. This will serve as a possible model system for novel magnetic information storage prototypes, whereas the study of the hybrid electronic properties will elucidate the possibility to engineer the graphene spin texture going towards its use as base material for spintronic applications.
