14082 IUPAC Gold Book - regular surface 10.1351/goldbook.14082 14082 current 1 Perfect surface of a solid without heterogeneity or defect. Rigorously speaking, this is a theoretical notion. In practice, however, this term is used to refer to local space regions of real relaxed and reconstructed surfaces if the perturbations caused by the nearest adjacent (surface) defects can be neglected.
