Scanning electron micrograph of (a) a typical set of as-grown wires and (b) the device. Scale bars are (a) 500 nm and (b) 100 nm. c Differential conductance, dI/dVsd, colormap of Yu–Shiba–Rusinov (YSR) subgap peaks evolving in plunger gate voltage, VP, and bias voltage, Vsd, across spinful charge state Z. Arrows indicate the position of the gap singularities. d Fit to Gaussians of YSR peaks at the electron-hole (e-h) symmetry point of Z. Temperature dependence of (e) peak position and (f) peak height, full width at half maximum (FWHM) extracted from fitting YSR peaks at the e-h symmetry point of four different charge states of doublet ground state, including Z. All datasets have been fitted to parabolas of the form y = a0 + a1T + a2T2, to indicate that they do not change faster than T2. g Temperature dependence of the product of peak height and FWHM scaled by their values at 30 mK. Error bars in e, f and g correspond to standard deviation.
