Abstract

We analyze a manifestation of the partial ordering transition of adatoms on graphene in resistivity measurements. We find that the Kekule mosaic ordering of adatoms increases the sheet resistance of graphene due to a gap opening in its spectrum and that critical fluctuations of the order parameter lead to a nonmonotonic temperature dependence of resistivity with a cusp-like minimum at T = T-c
