From: Topological Signatures in the Electronic Structure of Graphene Spirals
(red lines) Band structure for the graphene spiral ac[1]zz[0-2] (top panel) under the influence of an external electric field of intensity 0.6 V/Å and applied perpendicularly to its axial direction.
Horizontal line marks the Fermi energy (not shifted to zero). Dotted black lines are the energy dispersion for the same spiral for null electric field.
