Proximity induced superconductivity in graphene on SiC by intercalation (E1)
Project Description
Epitaxial graphene on SiC, which can be grown with high quality on an insulating substrate, provides excellent opportunities for applications as well as fundamental studies of graphene properties. The development of intercalation of different species into the interface between the SiC substrate and epitaxial graphene has greatly expanded these opportunities. In particular it opens an avenue for tailoring graphene properties by proximity coupling. In this project we will use the concept of intercalation to investigate the proximity coupling of epitaxial graphene to correlated states. In particular we will investigate (i) proximity induced superconductivity in graphene implemented by intercalated superconducting layers between SiC and graphene and (ii) the proximity induced interplay between Mott-Hubbard states of intercalated atomic superlattices and the overlying graphene.
