Abstract :
We describe an application of the many-body GW method to calculate the electronic band structure and optical properties of the clean Si(0 0 1) 1 × 2 surface and its changes upon antimony adsorption. We find that the so called (1 × 1) reconstruction of Si(0 0 1):Sb is actually a mixture of (2 × 1) and c(2 × 2)-Sb domains.
