Intrinsic second-order topological insulators in two-dimensional polymorphic graphyne with sublattice approximation
Z. J. Chen, S. G. Xu, Z. J. Xie +2
In two dimensions, intrinsic second-order topological insulators (SOTIs) are characterized by topological corner states that emerge at the intersections of distinct edges with reve…
