摘要: Abstract By applying the known variation of electric fields at metal surfaces to quantum mechanical, wave vector dependent, dielectric tensor we find that surface a has an anisotropic response. This anisotropy is interband electronic effect produced in layer atoms and very sensitive detailed band structure. It forms important part change reflectivity ΔR/R which found when submonolayer films various materials are adsorbed on surfaces.
