The electron-electron interaction near an interface

摘要: Abstract The application of many body techniques to interfaces is restricted by the labour involved in obtaining a screened interaction which valid interface region. To be realistic this must contain not only non-locality but also extra poles energy corresponding excitations. An approximation presented obtains terms bulk dielectric properties two media still has necessary mentioned above. are examined and shown correspond surface plasmon type excitations at interface. asymptotic form exchange correlation potential calculated using non-local classical image large distances from metal surface.
