The Fe/CaS/Fe (001) heterostructure.
Model for Fe/CaS (001) interface structures, IC1 interface configuration with Fe atoms sitting above Ca and S sites and IC2 with iron atoms located above hollow sites between Ca and S atoms (we note that for IC2 interface model the Fe1' and Fe2' atoms have similar atomic environments).
