概要
- 論文の詳細を見る
The scanning tunneling microscope (STM) has been used to study structural transformation of the Si(111)√3×√3(R30°)-Ag surface caused by atomic hydrogen adsorption. When atomic hydrogen adsorbs on the √3-Ag surface, the Ag atoms are expelled to form clusters. The size of the Ag clusters has been confirmed to be less than 150 Å in agreement with previous ion scattering results. Spatial distributions of the clusters observed as functions of the exposure to atomic hydrogen, reveal that surface diffusion of Ag atoms over the hydrogen-covered regions is largely suppressed compared with that on the √3-Ag surface. The clusters are hexagonal and their orientations suggest the formation of Ag(111) clusters.
