The morphology of the initial growth stage of Ag thin films on Mo(110) substrate was investigated in‐situ by the scanning electron microscope (SEM). A great majority of the Ag crystallites showed a truncated Wulff's equilibrium shape of the face‐centered‐cubic (fcc) structure with epitaxial orientation [ 1 0]Ag//[1 1 ]Mo, (111)Ag//(110)Mo with the substrate temperature of 400 °C. In‐situ SEM observation during the growth revealed two kinds of particular morphological change of Ag crystallites, namely (1) rotation of an Ag crystallite and (2) reformation of the crystal faces of the Ag crystallite. However, a small number of Ag crystal particles showed Wulff‐polyhedron truncated by the (100) plane parallel to the substrate surface (oriented to the 〈100〉 axis normal to the substrate surface).
