GapExtractor

GapExtractor© is a free software designed to determine the band gap energy of powder samples (semiconductors and insulators) by analyzing their diffuse reflectance (DR) spectra. This analysis is based on the Tauc-method and the DR theory developed by Kubelka and Munk. By downloading and using GapExtractor©, you agree to cite the software and the original source describing the method. Please cite them as: (1) A. Escobedo-Morales, I. I. Ruiz-López, M. de L.
