Have Mysterious Topological Valley Currents Been Observed in Graphene Superlattices?
Stephan Roche, Stephen R. Power, Branislav K. Nikolić +2
We provide a critical discussion concerning the claim of topological valley currents, driven by a global Berry curvature and valley Hall effect proposed in recent literature. After…

Valley current generation using biased bilayer graphene dots
Fionnuala Solomon, Stephen R. Power
Intrinsic and extrinsic valley Hall effects are predicted to emerge in graphene systems with uniform or spatially-varying mass terms. Extrinsic mechanisms, mediated by the valley-d…
