摘要

Low-energy electron diffraction and Auger electron spectroscopy were used to study the initial growth and the alloy formation of Ni ultrathin films on Pt(1 1 1) surface. Several interesting structural phases were observed in this system: pseudo-(1 × 1), (√3 × √3)R30°, coherent epitaxy, incoherent epitaxy, and (2 × 2). The phase diagram was determined by LEED. In addition, the formation of Ni-Pt alloy was investigated at various Ni coverages. The starting temperature for the alloy formation increases significantly as the Ni thin films turn into three-dimensional islands.
