Coadsorbate Induced Reconstruction of a Stepped Pt(111) Surface by Sulfur and CO: A Novel Surface Restructuring Mechanism Observed by Scanning Tunneling Microscopy

The chemisorption of sulfur and CO was found to have profound effects on the structure of s stepped platinum surface. By itself, sulfur chemisorbs, forming a {ital p}(2{times}2) ordered structure, and destabilizes the step structure by inducing doubling of the terrace widths and step heights. Subseq...
