WebJan 24, 2024 · Importantly, when a domain wall (DW) divides bilayer graphene into AB and BA stacking domains, a pair of states appears at each valley, connecting the valence and conduction band continua through the energy gap (figure 1 right) [21–23]. These gapless states are topologically protected if the valley index is conserved. WebMay 23, 2013 · The stacking of two graphene sheets exhibits analogous physics. Fig. 1A shows the energy of bilayer graphene as a function of the relative in-plane displacement u between the two graphene sheets, which we will use as a continuous-order parameter ().The energy as a function of u is maximal in the high-symmetry state (u = 0) where one … WebJun 26, 2024 · Layer-stacking domain wall in bilayer graphene is one type of topological defects that can greatly affect the electronic properties of bilayer graphene and therefore lead to nontrivial transport behaviors.
