Existence of nontrivial topologically protected states at grain boundaries in bilayer graphene: signatures and electrical switching

Wlodzimierz Jaskolski, Marta Pelc, Leonor Chico +1

Recent experiments [L. Ju et al., Nature, 2015, 520, 650] confirm the existence of gapless states at domain walls created in gated bilayer graphene, when the sublattice stacking is…
