EPITAXIAL-GROWTH OF COBALT FILMS ON CU(100) - A CRYSTALLOGRAPHIC LEED DETERMINATION

Epitaxial thin films of cobalt ranging from 1 ML Up to 10 ML have been grown on a Cu(100) substrate and characterized by LEED. The Cobalt is found to grow, adopting a slight tetragonal distortion of its high-temperature FCC phase. Further growth of 5 ML Cu on top of a 5 ML CO film results in an almost perfect Cu(100) surface.
