| Abstract: | Temperature dependence of dielectric constant (e')and dielectric loss (e") are studied in glassy Se70Te30-xAgxwhere x is varied from 0 to 10 in the
frequency range 1 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 T curve could be observed in
ternary Se70Te30-xAgx alloys. However, such
loss peaks could not be observed in binary Se70Te30
alloy, which indicates that Ag incorporation in binary system, is responsible
for such behaviour. This is explained in terms of [(D-) (Ag+)]
dipoles which otherwise were not present in the undoped samples. |
