Abstract: Temperature dependence of I-V characteristics and dc conductivity of Se85-xTe15Sbx (where x= 2, 4, 6, 8 and 10) glasses in the form of thin pellets has been studied. The pellets have been prepared from the ingots of glasses in the powder form. It is quite evident from I-V characteristics that the glass containing 4 at wt % of Sb allow maximum current to pass through itself as compared to its other counterparts of the series. The linear relationship between ln (I) and V1/2 strongly suggests the type of conduction as the Poole-Frenkel. The deviation from ohmic behaviour at lower voltages towards the non-ohmic behaviour at higher voltages is due to the additional thermal effects at higher temperatures induced in the sample. The electrical conductivity of these samples for the above-mentioned compositions using their I-V characteristics has been determined. The variations of electrical conductivity with composition at all temperatures show that Se81Te15Sb4 glass has the maximum conductivity. This variation is explained using the bonding between Se and Sb at different compositions. Hence, the composition Se81Te15Sb4 is more chemically ordered and electrically conducting as compared to other members of the series.
