Epitaxial growth of Ag on Ni 111/

Time of flight impact-collision ion scattering spectroscopy TOF-ICISS.have been used to investigate the heteroepitaxial growth of 3 ML of Ag on Ni 111.. We found that two different of preferred epitaxial growth exist depending on the substrate temperature during Ag deposition: Agw112xrrNiw112xand Agw112xrrNiw112x. These experimental results strongly suggest that the growth modes can be manipulated on the heteroepitaxial system, Ag 111.rNi 111. by controlling the substrate temperature during Ag deposition. q1998 Elsevier Science B.V.
