    Structure and dielectric behaviour of glasses in the TeO2-BaO-V2O5system
    (2021-02-16) Tasheva T.R.; Slavov S.S.
    The rapid development of telecommunication and information technology aims to design and investigate new functional materials. Glasses in the TeO2-BaO-V2O5 seems to be promising materials within this purpose. In this connection the structure and dielectric properties of the glasses have been studied. Small polaron hopping of V4+ to V5+ ion in the vanadate chains and the influence of BaO and TeO2 on the dielectric permittivity, dielectric losses and frequency depended conductivity of the glasses measured at room temperature in the frequency range from 100 Hz to 1 MHz have been discussed.
