Surfaces that are vicinal to high symmetry directions have frequently demonstrated their enormous potential for surface science research and applications. Vicinal surfaces characterized by arrays of atomic steps exhibit distinct chemical and physical properties, but they are also useful as templates for nanostructure growth, and, more generally, to transmit uniaxial and/or chiral symmetry to epitaxial layers. In this context, curved surfaces with a smooth variation of the vicinal angle, i.e., a tunable step lattice constant, allow a straightforward and rational investigation of all physical-chemical phenomena related to the presence of atomic steps. In particular, we have used curved noble metal surfaces to investigate the electron scattering problem at atomic steps on bare surfaces, monolayers and thin films, using Angle-resolved photoemission and micron-size light spots that are scanned over the surface. I will discuss through a number of cases the limits and advantages of using such curved surface approach for ARPES studies.
