Extended Data Fig. 3: Chequerboard patterns.
From: Evidence for chiral supercurrent in quantum Hall Josephson junctions
a–c, Differential resistance modulation with magnetic field and measured voltage showing a characteristic chequerboard pattern. d–f, Fourier transform amplitude at the chequerboard oscillation frequency as a function of the measured voltage. The orange curve is a fit to the data following the same procedure as in ref. 39. a,d, Junction DP24-D with fit parameters ETh = 640 μeV and x = 0. b,e, Junction HV88-C with fit parameters ETh = 240 μeV and x = 0.02. c,f, Junction HV88-F with fit parameters ETh = 140 μeV and x = 0.02.
