Solving the Long-Standing Cu(111) “8” Surface Oxide Puzzle
Due to the interesting properties of copper oxides, in particular for catalytic applications, ultrathin oxide layers formed by Cu oxidation have attracted sustained interest. Experimental observations of several surface phases, including the so-called “5–7”, “8”, “29” and “44” structures, have sparked ongoing debate....
