Electronic structure of Pb-intercalated graphene on Ir(111): an ab initio study
ORAL
Abstract
Extending graphene’s electronic properties beyond those intrinsically inherent to it is a great challenge of the contemporary condensed matter physics. In particular, because of graphene's extremely weak spin-orbit coupling, currently there is an intense research aiming at inducing pronounced spin-orbit effects in it \cite{\1,2,3}. We present the results of our \emph{ab initio} study of the graphene on Ir(111), intercalated by a monolayer of Pb atoms. We discuss system's crystal and electronic structures, as well as spin texture and analyse the influence of the intercalated Pb monolayer on the graphene $\pi$ bands.\\ \\ ${1}$ D. Marchenko et al.
