Study of optical spectra of semiconducting compound cuinse2 in wide energy region

Abstract

The precise reflectivity spectra of copper indium diselenide are obtained in energy range 1 to 5 eV at 80 K for polarized light (E^c, E||c*). For the first time the spectra for pure polarization E||c are evaluated. Optical functions in energy range 1- 23 eV are calculated using Kramers–Kronig transformations.
