Аннотация
Iron disulfide (FeS2) films with a wide range of electrical resistivities 100 Ω cm ⩽ ρ ⩽ 800 kΩ cm, a high adhesion to the substrate, and a resistance to aggressive media have been prepared by the spray pyrolysis of aqueous solutions of the salts FeCl3 · 6H2O and (NH2)2CS at low temperatures in the range 250°C ⩽ TS ⩽ 400°C. It has been found that the FeS2 films have a high transmittance T ≈ 60–70% and are characterized by a sharp transmission edge. It has been shown that the optical band gap for direct (Egop = 2.19–2.78 eV) and indirect (Eg′op = 1.26–1.36 eV) optical transitions depends on the conditions of film preparation.
