Abstract
Deposition of Co atoms on Au(111) surfaces leads to the formation of self-organized bilayerCo nanowires at the step edges between adjacent narrow Au(111) terraces. Scanningtunneling microscopy and spectroscopy at low temperatures is used to probe the influenceof the finite dimensions on the local density of states for both the Co wires and the narrowAu terraces. Confinement of Au surface state electrons to narrow Au terraces causes a shiftof the Au surface state onset energy to higher energies. For the Co nanowires discreteenergy levels are observed. Moreover, standing wave patterns occur at the surface ofboth the Au and the Co. The patterns increase in complexity with increasingenergy. All Co nanowires formed at the edges of narrow Au terraces reveal acharacteristic maximum in the local density of states at a significantly differentenergy when compared to the Co islands that are formed on large Au terraces. Theexperimental results can be interpreted in terms of a simple particle-in-a-box model.
