We present a study of the surface segregation at the (111) surface of a random Al50Zn50 alloy and a study of an AlZn alloy at the (111) surface of Al at zero temperature by means of the linear muffin-tin orbitals Green's-function technique. We find that zinc segregates in the surface layer and that the phase separation exists in the surface solid solution of random AlZn alloys.
