Evolution of BTK fitting parameters with temperature. The main graph shows the energy gap , including a fit to at for the planar Cu junction. The theoretical value for Pb is . Inset: The smearing parameter including parabolic fits to the data. The dashed line represents thermal broadening, where . Squares: planar ( and ). Crosses: planar ( and ). Circles: planar array ( and ). Down triangles: Two planar samples ( and ). Diamonds: point contact ( and ).
Results of the analysis. Main graph: Planar and point-contact junctions at 4 and , respectively. Insets: Planar samples at and a schematic cross section showing a part of the planar array of nanojunctions connected by a single top contact. Up triangles: point contact. Other symbols as in Fig. 1.
Results of the analysis for theoretical BTK curves for different parameter regimes. The labels indicate the polarization of the simulated spectra. Up triangles and squares represent a 20% increase in and , respectively, for the simulated spectrum. (a) Low and regimes, with parameters similar to the ones obtained for the planar junctions ( and ). (b) High and regimes, with parameters chosen to resemble a superconductor/semiconductor interface ( and ).
