摘要: Abstract Electronic and optical properties of 3d-transition metal adsorbed graphene system, theoretically studied in the framework density functional theory, reveals significant modification compared to pristine system. Due adsorption transition metal, emergence closely separated electronic bands leads substantial amount low energy absorption below 2.0 eV photon energy. Very enhancement static dielectric constant large value reflectivity regime has been identified for different systems. In systems, particularly up half filled d-shell atom, pronounced line deep ultraviolet beyond 30.0 eV is observed.
