  We study the problem of non-magnetic impurities adsorbed on bilayer graphene
in the diluted regime. We analyze the impurity spectral densities for various
concentrations and gate fields. We also analyze the effect of the adsorbate on
the local density of states (LDOS) of the different C atoms in the structure
and present some evidence of strong localization for the electronic states with
energies close to the Dirac point.
