“…By increasing the film thickness to more than 1 monolayer, the fcc metal forms (1 1 1) or nearly (1 1 1) monolayer on the bcc (1 1 0) surface with certain crystallographic orientations. The epitaxial orientations, despite the geometrical asymmetry, exist in the combination of the densely packed fcc (1 1 1) and bcc (1 1 0) planes; the so-called Kurdjumov-Sachs (K-S) and Nishiyama-Wassermann (N-W) orientation relationships have been experimentally observed in these interfaces, such as Ag, Au, Pd, and Pt on 11.191 Mo(1 1 0) [1][2][3] with K-S orientation and Ni, Pb, Ce, and Nd on Mo(1 1 0) [4][5][6][7] with N-W orientation. Interfacial energy calculations for elucidating the origin of the epitaxial orientation have also been performed on the fcc/bcc system [8,9].…”
