摘要：

We present the first results of a combined scanning tunneling microscopy (STM) and surface X-ray diffraction (SXRD) study of Ag monolayer deposited on Cu(111). The STM images of Ag monolayer show a periodic frame of triangles, 4 or 5 atomic row wide with 1 or 3 atoms protruding in the centre respectively. Away from the triangles, the corrugation of the atomic rows is about 0.05 Angstrom while the depth of the triangles is about 0.5 Angstrom. SXRD shows an "average" Ag surface unit cell (9.43 x 9.43) times the Cu(111) surface unit cell without rotation in good agreement with STM observations.
