We present a simple theory for quasiparticle band structures of semiconductor surfaces. Despite its simplicity the model includes contributions from electronic interaction with surface plasmons in addition to both local field and dynamic effects. Starting from the pseudopotential method within the local density approximation, the resulting quasiparticle band structure of GaAs(110) is in good agreement with a recent detailed theoretical work.
