Strain-enhanced two-photon absorption in twisted bilayer graphene
Abstract We theoretically investigate the strain-tuned moiré flat bands and two-photon absorption (TPA) in magic-angle (MA) twisted bilayer graphene (TBG). Using a low-energy continuum model for strained TBG and second-order perturbation theory, we demonstrate that uniaxial strain significantly modu...
