Abstract: In this paper, the dielectric properties of In₄₀SexTe₆₀₋x glassy alloys (x = 10, 20 & 30) have been reported. These measurements are carried out as a function of temperature and frequency in the range 120-350 K and 0.1-10 kHz respectively. The frequency and temperature dependence of dielectric constant Ɛ΄ and dielectric loss Ɛ΄΄ is almost similar in nature in all the alloys and the experimental results indicate that dielectric dispersion sets in at temperature exceeding 150 K and is more prominent at lower frequencies. Ɛ΄ and Ɛ΄΄ values as a function of temperature and frequency are maximum for x = 20 alloy, though similar behaviour is observed in all the samples. The experimental results seem to be explained in terms of the theory of dielectric dispersion based on two electrons hopping over a potential barrier. The frequency dependence of dielectric loss in present set of glasses at a fixed temperature is in good agreement with theory of dielectric dispersion.
