Abstract

We present a theoretical study of resonance characteristics in graphene from adatoms with s or p(z) character binding in top, bridge, and hollow positions. The adatoms are described by two tight-binding parameters: on-site energy and hybridization strength. We explore a wide range of different magnitudes of these parameters by employing T-matrix calculations in the single adatom limit and by ...
