DC SURFACE CONDUCTIVITY STUDIES ON Se BASED TERNARY CHALCOGENIDE GLASSY ALLOYS

Surface conductivity measurements, by means of I-V characteristics, of Se75Te25-xSnx (x=2, 4, 6 & 8) glassy systems have been studied at room temperature in thin film form. These glasses were prepared by melt quenching technique. Experimental results indicate that the conduction mechanism in these semi-conducting systems is of Poole-Frenkel type. The change in dc surface conductivity is attributed to the Se-Sn bond concentration in the Se-Te-Sn system. Also, the composition containing Sn6 at. wt. % shows the maximum conductivity in thin film form. This maximum conductivity could be explained on the basis of maximum concentration of high energy bonds. The system under test moves towards more chemically ordered material till 6 at. wt. % of Sn.
