|Title:||Dielectric relaxation in glassy Se<sub>70</sub>Te<sub>30-x</sub>Ag<sub>x</sub>|
|Abstract:||Temperature dependence of dielectric constant (e')and dielectric loss (e") are studied in glassy Se<sub>70</sub>Te<sub>30-x</sub>Ag<sub>x</sub>where <i style="">x</i> is varied from 0 to 10 in the frequency range 1<sub> </sub>to 10 kHz and temperature range 300-350 K. The results indicate that the dielectric dispersion exists in the above frequency and temperature range. Loss peaks in e" versus <i style="">T</i> curve could be observed in ternary Se<sub>70</sub>Te<sub>30-x</sub>Ag<sub>x</sub> alloys. However, such loss peaks could not be observed in binary Se<sub>70</sub>Te<sub>30</sub> alloy, which indicates that Ag incorporation in binary system, is responsible for such behaviour. This is explained in terms of [(D<sup>-</sup>) (Ag<sup>+</sup>)] dipoles which otherwise were not present in the undoped samples.|
