Properties of crystalline γ-TeO2 thin film

Incorporation of transition metals in the hot-wall-epitaxy growth of Bi2Te3and Sb2Te3

“…(The Raman spectra were measured under a weak laser excitation before and after the modification of the materials by the exposure to an intense laser light.) The peak at 422 cm −1 is associated with the bending vibration of the Te-O bonds in crystalline TeO 2 , whereas the peaks at 684 and 819 cm −1 are associated with the symmetrical stretching of the Te-O bonds [29,32]. We point out that the as-grown sample exhibited a broad peak in a range of 600-800 cm −1 , suggesting the presence of glassy oxides even prior to the generation of crystalline TeO 2 by the laser exposure [33].…”

Chemical Bonding and Hybridization in 5p Binary Oxide

“…The wide variety of electronic and chemical properties of metal oxides make them very exciting materials both for basic research and for technological applications. − Oxides cover a wide range of electrical properties from wide band gap insulators to conductors and superconductors . 5 p binary oxides (SnO 2 and In 2 O 3 being the most well-known) belong to a class of materials that combines high electrical conductivity with optical transparency (“transparent conductors”) and, thus, constitute an important component for optoelectronic applications .…”

Microstructural characterization and crystallization of (1−x)TeO2–xCdF2 (x=0.10, 0.15, 0.25mol) glasses

“…14 The present study has shown that it is possible to obtain amorphous structures with higher concentrations of CdF 2 content. Preliminary experimental results of the present investigation demonstrated the effect of the heating rate, annealing temperature and CdF 2 content on the thermal and the microstructural properties of TeO 2 -CdF 2 binary glasses.…”
