Abstract
The result of the measurement of the thermoelectric power of glasses in the As 2Se 3As 2Te 3 system are reported. The results indicate that towards the As 2Te 3 end of the composition, there is an anomalous increase in thermoelectric power, the origin of which is not clear. Polaron hopping seems to contribute to conductivity in tellurium rich glasses. Structural restrictions on polaron hopping, such as the availability of AsTeAsTe chains seems to be important in discussing transport behaviour.
