Paper Abstract

Iron pyrite thin films have been obtained by flash evaporation. Properties of the films are modified by annealing them in a sulfur atmosphere. Here we present some results on the influence of the annealing temperature (250 degree(s)C <EQ Ts <EQ 450 degree(s)C) on the optical properties of two groups of samples with thickness approximately equals 0.35 micrometers and approximately equals 1.00 micrometers , respectively. Sulfuration temperature has a clear influence on the optical absorption of the films. Two maxima at energies approximately equals 4.0 eV are observed in the reflection spectra, similar to those found with single crystals but the peaks intensities vary with Ts. Results are discussed by considering the enhanced stoichiometry and crystallinity of the films.
