| Abstract | The electron emission produced by the grazing incidence of ultrashort laser pulses on two faces of aluminum, Al(100) and Al(111), is investigated using the band-structure-based-Volkov (BSB-V) approximation. The present version of the BSB-V approach includes not only a realistic description of the surface interaction, accounting for band-structure effects, but also effects due to the induced potential that originates from the collective response of valence electrons to the external electromagnetic field. For both crystallographic orientations we found that the induced potential contributes to the emergence of band-structure signatures in the near-threshold region of photoelectron spectra. This result opens a window to scrutinize band-structure effects in metal surfaces via ultrashort-laser interactions. |
