EnglishThe bulk terminated Cu(100) surface becomes unstable in the presence of CO at room temperature when the pressure reaches thembar range. Scanning tunneling microscopy images showthat above 0.25mbar the surface forms nanoclusters with CO attached to peripheral Cu atoms. At 20 mbar and above 3-atom wide one- dimensional nanoclusters parallel to b001N directions cover the surface,with CO on every Cu atom, increasing in density up to 115 mbar. Density functional theory explains the findings as a result of the detachment of Cu atoms fromstep edges caused by the stronger binding of CO relative to that on flat terraces.

| Abstract: | The bulk terminated Cu(100) surface becomes unstable in the presence of CO at room temperature when the pressure reaches thembar range. Scanning tunneling microscopy images showthat above 0.25mbar the surface forms nanoclusters with CO attached to peripheral Cu atoms. At 20 mbar and above 3-atom wide one- dimensional nanoclusters parallel to b001N directions cover the surface,with CO on every Cu atom, increasing in density up to 115 mbar. Density functional theory explains the findings as a result of the detachment of Cu atoms fromstep edges caused by the stronger binding of CO relative to that on flat terraces. |
