Abstract

Growth of surface alloys offers a crystal system freedom to adopt structures which may not be available to the bulk material. To investigate how this freedom is exercised an investigation of the growth of Pd on Cu(001) and Al on Pd(001) has been performed. These surfaces develop a p4g structure which has as a principal driving force the size mismatch between the elements. Proof of the role of driving force will be given by careful codeposition studies. LEED analysis of the two alloys reveals a basic similarity of structure, however ion scattering measurements reveal fundamental differences in the arrangement of surface layer atoms.
