Influence of the surface band structure in photoelectron emission by ultra-short laser pulses

Photoelectron emission from the valence band of aluminum and beryllium surfaces by ultra-short laser pulses is studied within the Band-Structure-Based - Volkov (BSB-V) approximation, which takes into account the contribution of the band structure of the solid. We found that band structure effects are extremely important for Be(0001), for which signatures of partially occupied surface states can be observed in the electron emission spectra.
