Surface photoeffect: photoabsorption of surface and image states

摘要: The surface photoeffect of Al(001) is studied for a p continuous laser in the long wavelength (LWL), i.e. λ ≥ 100 A. Perpendicular to gas–solid interface potential, electron density, and consequently fields, vary at atomic scale LWL approximation, corresponding constant space does not apply. vector potential associated with these written temporal gauge U = 0, obtained by solving Maxwell material equations. In present model dielectric function, entering equations, dependent on density ρ(z) perpendicular calculated from Schrodinger equation bulk constant. Using spatially varying photoabsorption spectrum surface, Fermi first image states are using golden rule. For time case realistic yield analysed i...
