Fig. 3. Helicity-dependent current behavior under different source-drain voltage geometries.

Fig. 3

The peak of the helicity-dependent current Îx [⟳ - ⟲] measured as a function of a, transverse source-drain voltage Vy and b, longitudinal source-drain voltage Vx. The graphene Fermi level was gated to the Dirac point (EF = 0). Solids lines are linear fits.
