Figure 2: Full superconducting gaps and theoretical fittings.

(a) The topography of the superconducting area with quite dense Sr clusters. Scale bar, 10 nm. (b) The spatially resolved tunnelling spectra taken from a series of points equally spaced along the arrowed line in a at 400 mK, I_t=102 pA. (c) The averaged and normalized spectrum of the spectra in b. The solid curve is the theoretical fitting with Dynes model using two components (s wave and ani-s wave). (d) The comparison of theoretical fittings with different superconducting gap functions.
