Optical functions and electronic structure of CuInSe2, CuGaSe2, CuInS2, and CuGaS2

M. I. Alonso, K. Wakita, J. Pascual +2

We report on the complex dielectric tensor components of four chalcopyrite semiconductors in the optical energy range (1.4-5.2 eV, from 0.9 eV for CuInSe2) determined at room tempe…
