We demonstrate the topological properties of the band-gap of armchairgraphene nanoribbons in a spatially varying staggered sublattice potential.Several general scaling laws are presented to quantify the band gap variation.It is found that all armchair nanoribbons are described by one of threedistinct classes depending on their width, one of which is the well knownmassless Dirac condition, and the other two we call potentially gapless, andgapless-superlattice. We construct an effective theory which faithfullyreproduces these results, and makes explicit the nature of the competing massesand overlap integrals across a particular sample. Finally we propose severalsystems on which these results should shed considerable light, and which haveall already been experimentally realized.
