DC electrical conductivity, thermoelectric power measurements of TiO2-substituted lead vanadate glasses

KV Ramesh, DL Sastry - Physica B: Condensed Matter, 2007 - Elsevier
Glasses of the system x (TiO2)(50− x) PbO: 50V2O5 were prepared by melt-quench process
in the range x= 0–15mole%. Measurements are reported for DC electrical conductivity as
well as thermoelectrical power for the above compositions in the temperature range 27–
227° C. The experimental results are analyzed with reference to various theoretical models
proposed for DC electrical conduction in amorphous semiconductors. The analysis shows
that at high temperatures, the temperature dependence of DC conductivity is consistent with …
