摘要：

A Scanning tunneling microscopy study of the ordered alloy Pt3Sn is presented. The (111) surface shows a bulk terminated p(2x 2) structure or a (root 3 x root 5) R30 degrees reconstruction, depending on preparation conditions. In addition, the reconstructed surface exhibits a mesoscopic honeycomb network. The network indicates the presence of subsurface dislocations, which are induced by a tin depletion due to preferential sputtering. On the p(2x2) structure small islands with uniform size are found, which are attributed to segregated tin. [S0163-1829(98)50948-4].
