Abstract
Se0.9In0.1 samples were prepared from their highly pure constituents, by ice-water quenching from the melts. Structural characterization using XRD and DTA has revealed a stable phase consisting of some crystalline clusters embedded in a glassy matrix with a single glass transition (Tg) at a temperature 320 K, an onset exothermic crystallization peak at 361 K, and a melting endotherm with a melting point at 473 K. The dc (ohmic contact region) and ac (50 Hz-80 kHz) conductivities were measured under vacuum as a function of temperature (from T < Tg down to LN2) for massive samples, 0.3-0.6 mm thick. Results of the space-charge-limited current and the electrical characteristics of both dc and ac conduction are given and discussed in the light of the temperature dependence of the conduction mechanism.
