✦ Synopsis

Lateral superstructures with honeycomb or square symmetries, as a model for the two-dimensional (\pi) electron sea in organic crystals or atomistic quantum dot arrays, are shown to be classified, with a simple criterion, into semimetals with gapless (k)-linear dispersions, semiconductors and metals. In some of the classes the symmetry enforces dispersionless bands to exist, which implies the occurrence of spin ferromagnetism when the electron correlation is turned on. These provide a unique opportunity for band structure engineering.
