We find that the states near the Fermi energy at the {Gamma} point on the 2D First Brillouin zone found in recent experiments are directly related to this contraction. In general, our calculation shows a better agreement with experiment than previous work. The remaining small differences might be attributable to a possible smaller but non-negligible contraction of the second interatomic layer distance.
