The adsorption of L- and DL-alanine on the Cu(001) surface under an ultrahigh vacuum environment has been studied by means of scanning tunneling microscopy (STM). From both the as-adsorbed and the annealed surface it has been found that L-alanine can form only the c(2x4) superstructure on the Cu(001) terraces while it can induce step faceting to <310> directions as well as further bunching of...
Adsorption of glycine on the Cu(001) surface has been studied with scanning tunneling microscopy. In addition to confirming the Cu(001)c(2x4)-glycine to be the major superstructure on the surface, it has been found that on the surface all steps are faceted to <310> directions and that the faceted steps may bunch together to form Cu{3117}1x1-glycine facets. On the basis of our STM images and...
