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: Ag[112]//Ni[112] and Ag[112]//Ni[112]. These experimental results strongly suggest that the growth modes can be manipulated on the heteroepitaxial system, Ag(111)/Ni(111) by controlling the substrate temperature during Ag deposition.
