Query: Impurity resonance effects in graphene $vs$ impurity location,
  concentration and sublattice occupation   Unique electronic band structure of graphene with its semi-metallic features
near the charge neutrality point is sensitive to impurity effects. Using the
Lifshitz and Anderson impurity models, we study in detail the disorder induced
spectral phenomena in the electronic band structure of graphene, namely, the
formation of resonances, quasi-gaps, bound states, impurity sub-bands, and
their overall impact on the electronic band restructuring and the associated
Mott-like metal-insulator transitions. We perform systematic analytical and
numerical study for realistic impurities, both substitutional and adsorbed,
focusing on those effects that stem from the impurity adatoms locations (top,
bridge, and hollow positions), concentration, host sublattice occupation,
perturbation strengths, etc. Possible experimental and practical implications
are discussed as well.
