Beyond the surface atlas: A roadmap and gazetteer for surface symmetry and structure

Having thus established a secure framework via ideal bulk-terminated crystalline surfaces, we subsequently demonstrate its extension to real surfaces. In considering how these differ from ideal surfaces we discuss relaxation and reconstruction within the same symmetry-resolved and structure-resolved perspective, drawing on numerous examples from the literature. Finally we illustrate the application of our scheme in one selected branch of surface science by exploring the symmetry-constraints on the surface chemistry of chiral molecules at chiral substrates.
