“…Recently, an experimental study combining simultaneous surface X-ray diffraction and stress measurements has demonstrated that a considerable rearrangement of the W(110) surface atoms takes place upon deposition of the Ni(111) overlayer [10]. Like the Ni/W(110) system, Ni/Mo(110) grows in the Nishiyama-Wassermann epitaxial orientation [11] and also undergoes a (1 × 1) → (8 × 1) → (7 × 1) series of structural transitions for submonolayer coverage at room temperature [12][13][14]. The growth proceeds in a layer-by-layer fashion at 115 K and 300 K, with agglomeration into three-dimensional clusters and alloying occurring upon annealing above 600 K [12,15].…”
