Photoelectron emission (PE) from the valence band of a metal surface due to the grazing incidence of ultrashortlaser pulses on two faces of aluminum- Al(100) and Al(111) - is investigated in the framework of a distorted-wave formulation.We use the band-structure-based-Volkov (BSB-V) approach [1], including also induced-potential effects originated from theelectron response of the surface to the external field. For both crystallographic orientations we found that the induced surface(IS) potential contributes to the emergence of band-structure signatures in the near-threshold region of photoelectron spectra.
