摘要：

The interaction of small molecules such as H-2 and O2 with Cu and Ni surfaces has been investigated with scanning tunneling microscopy. The results are reviewed with special emphasis on the observed similarities between the different adsorption-induced reconstructions and on the wide variety of formation mechanisms. New results for the adsorption of S on Cu surfaces are presented. On Cu(111) we have determined a previously unknown phase with a large unit cell. On the Cu(110) surface, an uncommon mass-transport sequence has been observed, and a model for one of the S adsorption-induced structures (the p(5 x 2) phase) is discussed.
