| description |
In this paperwe present the study of the glassy systems of formula: xMgO(1−x)(0.5V<sub>2</sub>O<sub>5</sub>·0.5MoO<sub>3</sub>)2TeO<sub>2</sub>,with (0 b x b 1). The aim of the work is to understand the relationship between in the induced changes in the glassy matrix by the incorporation of MgO in a vanadium–tellurite glass and the electrical response of the material. It has been found that the incorporation of MgO in the glassy matrix raises the glass transition temperature. The whole system's electrical behavior is explained by the small polaron hopping, in good agreement with the variable range polaron hopping model. In this matrix, an ionic transport by Mg<sup>2+</sup> is not allowed. The study gives an opportunity to understand how to tune in the middle-range glassy structural order and, as a direct implication, how to control the electrical conduction process. |
