Local currents in compound 16-OFF (top panel) and 16-ON (bottom panel), where the cross-sectional area of the cylinder is proportional to the current density. Red currents represent positive transport direction, and blue currents represent negative direction. The currents are calculated at the Fermi energy ((μL + μR)/2), but a small positive bias voltage is assumed for calculation purposes. For a full derivation see Okabayashi et al.44 and Paulsson and Brandbyge.42
