Figure 6: Energy spectroscopy on spin-dependent potential as a function of source-drain bias voltage with/without an external magnetic field.
From: Spin–orbit induced electronic spin separation in semiconductor nanostructures
The dotted white lines are traces of the energy crossings between the spin-dependent potential energy and the source/drain chemical potentials. The colour scales on the right indicate the differential conductance: 5 to 15 (ΩV)−1 for the experiment and 0 to 1.5 (ΩV)−1 for calculations. (a) Differential conductance dG/dVSG as functions of Vsd and VSG at Bex=0 T and T=0.22 K. (b) dG/dVSG as functions of Vsd and VSG at Bex=+8 T and T=0.22 K. (c) Calculated differential conductance as functions of Vsd and normalized electron energy 
at Bex=0 T. (d) Calculated differential conductance as functions of Vsd and normalized electron energy at Bex=+8 T.
