Induced-field enhancement of band-structure effects in photoelectron spectra from Al surfaces by ultrashort laser pulses

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 su...
