Abstract | The dielectric function data for CuGaSe2 and CuInSe2 have been modeled for both perpendicular (E ⊥ c) and parallel (E ∥ c) polarizations. We employ the modified Adachi's model dielectric function model with variable broadening. Variable broadening is accomplished by replacing the damping constant Γ with the energy-dependent expression Γ(E), where the shape of the broadening function is determined by two adjustable model parameters. In spite of one additional parameter per transition, this model requires fewer parameters than the conventional Adachi's model to achieve equal or better agreement with the experimental data. Our calculations give the relative rms errors for the real and imaginary parts of the index of refraction, δn and δk, equal to 0.9% and 9.5% for CuGaSe2 (E ⊥ c), 0.8% and 7.3% for CuGaSe2 (E ∥ c), 1.1% and 3.0% for CuInSe2 (E ⊥ c), and 2.5% and 3.7% for CuInSe2 (E ∥ c), respectively. |
