• Standardized extraction of optical band gap and urbach energy in zno and al-doped zno thin films from uv–vis spectra: an in-silico workflow (2026) · doi

  A targeted sensitivity study is needed to identify regimes where EU becomes unstable and to define conservative acceptance/rejection criteria for experimental datasets, considering noise level, baseline drift magnitude, and thickness uncertainty.

• Standardized extraction of optical band gap and urbach energy in zno and al-doped zno thin films from uv–vis spectra: an in-silico workflow (2026) · doi

  Future work should validate the workflow on measured UV–Vis and ellipsometry datasets, extend the model to interference/scattering corrections, and test sensitivity to thickness uncertainty and alternative objective window-selection criteria.
