Figure 3.

Visualization of the most transmitting eigenchannel wave function (incoming from the left electrode) at the Fermi energy for the junctions with compound 2a. OFF state shown in the top panel and ON state in the bottom panel. The isosurfaces of the eigenchannel wave function are colored according to phase and sign, the positive/negative real part being colored in deep-purple/light-blue (the imaginary part is below the cutoff value and not visible), and both junctions plotted with the same isovalue to be comparable.
