Graphene zigzag ribbons, square lattice models and quantum spin chains
Mahdi Zarea, Nancy Sandler
We present an extended study of finite-width zigzag graphene ribbons (ZGRs) based on a tight-binding model with hard-wall boundary conditions. We provide an exact analytic solution…

Quantum spin Hall phase in neutral zigzag graphene ribbons
Mahdi Zarea, Nancy Sandler
We present a detailed description of the nature of the wavefunction and spin distribution of the zero energy modes of zigzag graphene ribbons (ZGRs) in the presence of the intrinsi…

Rash spin-orbit interaction in graphene and graphene zigzag nano-ribbons
Mahdi Zarea, Nancy Sandler
We investigate the effects of Rashba spin-orbit interactions on the electronic band-structure and corresponding wave-functions of graphene. By exactly solving a tight-binding model…
