抄録

<p>The buried interface structure was found to cause faint 3×3 periodic ripples in scanning tunneling microscope (STM) at the surface of ultra-thin Ag films on the Si(111)√3×√3-B substrate. The ripples were purely geometric, since they showed no bias voltage dependence. X-ray diffraction revealed that the Ag/Si lattice commensuration introduces the 3×3 periodic displacement to the bottom layer of the Ag film. The displacement was also found to be transferred to upper layers in the Ag film while damping. It manifests itself as the 3×3 faint ripples on top of the Ag film in STM.</p>
