Fundamental principles for the development of new functional nanocomposite materials based on oxide 3D nanostructures for applications in THz optics and information transfer
Résumé
The purpose of this work is development of the solid-state materials possessing a small absorption combined with sufficient refraction index in the THz range. The main criteria, which were used for the material selection, were quite simple: inorganic compound with strong chemical bonds, stoichiometric composition, small concentration of delocalized charge carriers and sufficient polarizability over THz frequency range. It is obvious, that inorganic materials match these criteria in the greatest degree and, first of all, stable oxides with a high fusion temperature: Al2O3 , SiO2. In this work we studied monolithic nanofibrous alumina for the THz frequency range, which synthesis process was previously developed.
