Superstructure formation and faceting in the Cu(210)-O system studied by scanning tunneling microscopy

The interaction of O on Cu(210) has been investigated by scanning tunneling microscopy. Adsorption at room temperature followed by high-temperature annealing leads to a series of mesoscopic superstructures ordered on different length scales ranging between 15 and 150 {}. By contrast, adsorption at high temperatures leads to the formation of a (2×1) superstructure similar to that found on Cu(110).
