(color online) Band structures of the WS2/graphene heterostructure under different strains. Blue and red denote the contributions from WS2 monolayers and graphene, respectively. Panels (a)–(g) show the strains of 2%, 4%, 6%, −2%, −4%, and −6%, respectively. The Fermi level is set to be zero and denoted by green dotted line.
