Özet:

 

In this paper we report the effect of metallic Zn and In  additives on the electrical and dielectric properties of  Se0.85Te0.15 glassy system.  The temperature and frequency  dependence of the dielectric parameters in glassy Se0.85Te0.15,  Se0.75Te0.15In0.10 and Se0.75Te0.15Zn0.10 alloys are  studied by measuring capacitance and dissipation factor in the  frequency range (1 kHz--5 MHz) and temperature range (300--350 K).  Direct current (dc) measurements were also performed in the aforesaid  temperature range to assess the dc conduction losses.  Results are  interpreted in terms of a theoretical model which is based on two  electron hopping over a potential barrier and is applicable in the  present case.  Dielectric constant \varepsilon\prime, dielectric  loss \varepsilon\prime\prime and loss tangent d are found  highly frequency and temperature dependent.  Dependence of electrical  and dielectric parameters on the additives has also been found in the  present glassy system and has been discussed in terms of  electronegativity difference between the elements used in making the  aforesaid glassy system.
