Dirac cone move and bandgap on/off switching of graphene superlattice
Using the density functional theory with generalized gradient approximation, we have studied in detail the cooperative effects of degenerate perturbation and uniaxial strain on bandgap opening in graphene. The uniaxial strain could split π bands into π(a) and π(z) bands with an energy interval E(s)...
