Helical edge states and edge-state transport in strained armchair graphene nanoribbons

Helical edge states and edge-state transport in strained armchair graphene nanoribbons

Abstract A helical type edge state, which is generally supported only on graphene with zigzag boundaries, is found to also appear in armchair graphene nanoribbons in the presence of intrinsic spin-orbit coupling and a suitable strain. At a critical strain, there appears a quantum phase transition fr...
