The authors of the article "Substrate-induced bandgap opening in epitaxial graphene" published in *Nature Materials* (2007) have provided a corrigendum to correct and expand the references in their original article. Specifically, they have added references 20 and 21 to the first paragraph regarding single-layer and bilayer graphene, and references 7 and 8 to discuss gaps in graphene ribbons. Additionally, they have included references 6–9 to address the theoretical work on gap opening by breaking carbon sublattice symmetry. These corrections enhance the scientific context and provide additional references for further reading.The authors of the article "Substrate-induced bandgap opening in epitaxial graphene" published in *Nature Materials* (2007) have provided a corrigendum to correct and expand the references in their original article.
