Soliton fractional charge of disordered graphene nanoribbon
Y. H. Jeong, S. -R. Eric Yang, M. -C. Cha
We investigate the properties of the gap-edge states of half-filled interacting disordered zigzag graphene nanoribbons. We find that the midgap states can display the quantized fra…
Gap states and edge properties of rectangular graphene quantum dot in staggered potential
Y. H. Jeong, S. -R. Eric Yang
We investigate edge properties of a gapful rectangular graphene quantum dot in a staggered potential. In such a system gap states with discrete and closely spaced energy levels exi…
Topological end states and Zak phase of rectangular armchair ribbon
Y. H. Jeong, S. -R. Eric Yang
We consider the end states of a half-filled rectangular armchair graphene ribbon (RAGR) in a staggered potential. Taking electron-electron interactions into account we find that, a…
Graphene nanosystems and low-dimensional Chern-Simons topological insulators
Y. H. Jeong, S. -R. Eric Yang
A graphene nanoribbon is a good candidate for a Chern-Simons topological insulator since it obeys particle-hole symmetry. We show that in a finite semiconducting armchair r…
