Figure 4: Fraunhofer data.
From: Symmetry protected Josephson supercurrents in three-dimensional topological insulators
Critical supercurrent Ic versus perpendicular magnetic field B at T=16 mK for device 1 at different gate voltages, showing clear Fraunhofer diffraction patterns. The minima occur at intervals of Ф/Ф0~0.23 n, where n is an integer; however, we plot Ic versus B rather than Ф/Ф0 because the short junction area may be ill-defined due to flux focusing26.
