We have studied the correlation between the tribological properties and the structural changes of polycrystalline Ag films deposited on the Si(111)√<3>×√<3>-Ag reconstructed surface that was formed by one atomic layer of Ag atoms chemically bonded to each of the topmost Si atoms of the substrate. As a result, the Ag crystallites in the film are oriented to <111> direction of the substrate due to frictional effect (tribo-assisted reorientation) under the elastic-contact condition, when the film thickness was less than 10 nm in average. In addition, we have demonstrated that the re-deposited Ag film grows epitaxially on the reoriented surface, and that the difference in the degree of orientation can be controlled between the reoriented area and the non-reoriented area by controlling the surface composition of the substrate. These findings show the feasibility of novel film processing technology due to tribo-assisted reorientation.

研究了沉积在Si（111）&lt;$× &lt;$-Ag重构表面上的多晶Ag膜的结构变化与摩擦学性能之间的关系<3><3>。结果，<111>当膜厚度平均小于10 nm时，在弹性接触条件下，由于摩擦效应（摩擦辅助的再取向），膜中的Ag微晶取向为基板的方向。此外，我们已经证明，再沉积的Ag膜外延生长的再取向的表面上，并且可以通过控制衬底的表面组成的再取向区域和非再取向区域之间的取向度的差异进行控制。这些研究结果表明，由于摩擦辅助重取向的新的膜处理技术的可行性。
