Summary:Vicinal noble metal surfaces with regular arrays of steps and terraces are very convenient model systems to test the electronic properties of lateral nanostructures. Using angle-resolved photoemission with synchrotron radiation we thoroughly characterize electronic states and wavefunctions in a variety of vicinal Cu(111) and Au(111) surfaces. By tuning the terrace width, we can observe the fundamental transition from arrays of non-interacting nano-objects (terraces), where electron states are confined, to lateral coupling between terraces, which leads to superlattice states.
