(a) The dI/dV curves taken at 5 K are divided by that taken at the same location at 16 K. The SC gap feature is present in every location of the sample, indicating it is a bulk phase. (b) The spatially averaged spectrum shows that the coherence peaks are located at V=±5 mV. (c) Normalized spectra and (d) its spatial average of the 10 K dI/dV curves. The SC gap features are still present everywhere although the gap is significantly filled by thermal excitations.
