Periodically rippled graphene: growth and spatially resolved electronic structure
(American Physical Society, 2008-12)
We grow epitaxial graphene monolayers on Ru(0001) that cover uniformly the substrate over lateral distances larger than several microns. The weakly coupled graphene monolayer is periodically rippled and it shows charge ...
Theory of scanning tunneling microscopy of adsorbed molecules on metallic surfaces for nearly localized atomic states
(American Physical Society, 2011-04)
We consider a Hubbard-Anderson model which describes localized orbitals in five different sites hybridized both among themselves and with a continuum of extended states. A square planar geometry with an atom at the center ...
