Scanning tunneling microscopy has been applied to an atomistic scale investigation of the oxygen-induced restructuring of a Cu(100) vicinal surface, close to (610) but with average step orientations 10 degrees away from . The initial changes upon oxygen adsorption are found to be step-edge faceting to  and , and  step coalescence to form small (410) facets. Annealing enlarges these (410) facets while the much shorter  steps coalesce to form (401) facets. The implied strong energetic favouring of (100) step-edges in the presence of oxygen is attributed to the formation of Cu-O-Cu-O linear chains, known to be the stable element of oxygen-induced reconstruction of the (110) and (100) copper surfaces.
