Abstract:Processes of oxidation in the films Bi 2 Te 3 used in the various thermoelectric film devices working on air at various temperatures are investigated. Samples Bi 2 Te 3 of p-type thickness received 0,5-1,5 microns a method of discrete evaporation with additional homogenization of a steam phase. Changing technological conditions to raise dust and tempering, have received samples with a wide set of concentration of carriers of a charge from 5х10 18 up to 6х10 19 cm -3 . The fact of formation oxide layers proves to be trues the data electronography the analysis. The electronogram tempering samples alongside with dot reflexes from monocrystal blocks have the continuous polycrystalline rings adequate to a phase of structure Bi 2 O 3 . The method of diffraction electron with high energy -electrongraphy investigates formation of phases in the film condition, received by joint evaporation the components of system Bi -S. Experimentally investigated dependence of the near nuclear order in amorphous layered Bi 2 S 3 from conditions of reception of thin layers -besieged as under influence on molecular pair an external electric field intensity 3000Vxcm -1 , and outside of a field. It is established, that internuclear distances and radiuses of coordination spheres in layered, received in conditions of influence of an electric field, are a little shortened in comparison with those without influence of a field.

“…Illumination supports these materials to exhibit change in their refractive indices that is important in the data for holography storage and in fabricating several integrated components, e.g. optical filters, mixers, couplers, and modulators [11][12][13]. Furthermore, studies of chalcogenide semiconducting materials have received attention because of the material's uses in reversible phase change applications.…”

Chalcogenide amorphous thin films of the modification (As 2 S 3 ) 0.95 Cu 0.05 were prepared using a thermal evaporation technique. The optical properties of the resultant films were investigated based on the transmittance spectra in the photon energy range 1.6-2.82 eV. Thicknesses of the films under study were determined using the envelope technique based on the transmittance spectra. The optical measurements were carried out over the conditional temperature extending from 77 to 300 K. The results of the mentioned measurements are conductive tools in investigating the electronic structures of the Chalcogenide Glasses, however the analysis of the experimental results provide information about the optical gap width and elucidate the broadness of the band tail that may disturb the band gap edges. Moreover, the single-effective oscillator was implemented in calculating both the oscillation and dispersion energies of the films under investigation. The static refractive index and the static dielectric constant were also determined for these films.

“…Chalcogenide glasses have been found to exhibit the change in refractive index under the influence of light, which makes it possible to use these materials to record not only the magnitude but also the phase of illumination. The latter is especially important in holographic optical data storage and in the fabrication of various integrated components and devices such as selective optical filters, mixers, couplers and modulators [5][6][7]. Most of the work has been carried out on chalcogenide thin films having Te as a major constituent.…”
