Topological Edge States at a Tilt Boundary in Gated Multilayer Graphene
Topological Edge States at a Tilt Boundary in Gated Multilayer Graphene
Despite much interest in engineering new topological surface (edge) states using structural defects, such topological surface states have not been observed yet. We show that recently imaged tilt boundaries in gated multilayer graphene should support topologically protected gapless edge states. We approach the problem from two perspectives: the microscopic perspective …
