Ordered Vacancy Network Induced by the Growth of Epitaxial Graphene on Pt(111)

Published in Phys. Rev. Lett. by ESISNA

Graphene is one of the most outstanding materials of the decade. Among all the different proposed applications and protocols to growth it, epitaxial graphene on single-crystal metal surfaces have acquired a significant relevance as a model system where to rationalize their atomic structure, interaction with the support and excellent electronic properties. However, there are still many fundamental incertitudes about their interaction with the supporting substrate.

Here we present a full atomic determination of a new graphene phase with low crystallographic ratio with the substrate. The Pt substrate “adjusts” the position of their surface atoms to accommodate the graphene layer.
