Andreev Reflection Spectra to Superconducting Gap Estimator
This refers to the voltage bias at which significant features (e.g., peaks, sharp changes) in the differential conductance (dI/dV) curve due to Andreev reflection are observed. For many s-wave superconductors, these features typically appear at voltages related to the superconducting energy gap (Δ).

Disclaimer: This tool provides a simplified estimation based on characteristic voltage bias. A precise determination of the superconducting gap from Andreev reflection spectra typically requires fitting experimental data to a theoretical model (e.g., Blonder-Tinkham-Klapwijk model), which accounts for various factors like interface transparency and temperature broadening.
