The result of the measurement of the thermoelectric power of glasses in the As2Se3-As2Te3 system are reported. The results indicate that towards the As2Te3 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 As-Te-As-Te chains seems to be important in discussing transport behaviour.
