Fig. 4. Tunable superconducting diode effect and scalable rectification.

Fig. 4

a Color maps of the magnetic field and AC current-dependent rectification voltages measured under negative magnetic fields with reversed polarities of flux-quanta (corresponding to the reverse of Fig. 1d). The inset demonstrates the switching between on, off, and reverse polarity of the rectification. b Rectification amplitude at various temperatures in a magnetic field of 40 Oe.
