Composition Dependent Of Dielectric Properties In Se_{100-X}Pb_X Glassy Alloys, Jyoti Sharma, Santosh Kumar

Turkish Journal of Physics

In this paper we report the composition dependent of dielectric properties in Se_{100-x}Pb_x (x = 0, 2, 4, 6 and 10) glassy alloys. The temperature and frequency dependence of the dielectric constants and the dielectric losses in the above glassy systems in the frequency range 1 kHz-5 MHz and temperature range 300-340 K have been measured. It has been found that dielectric constant and the dielectric loss both are highly dependent on frequency and temperature and also found to be increased with increasing concentration of Pb in pure amorphous Se. The results have been interpreted in terms of increase in …
