Abstract

Comparison of bandgap determination using ellipsometry and ELS-XPS. • Large energy bandgap difference between the two methods, up to 1.6 eV. • Combination of the two techniques, using a triple Tauc-Lorentz oscillator model. • Robust determination of the bandgap in the SiO 2-Si 3 N 4 system. • Method to measure n and k in a large energy range, from 1.5 up to 30 eV.
