Abstract

Ag1∓xSnSb1+xTe3 with a combination of thermoelectric properties was investigated. This compound is a non-stoichiometric derivative of AgSnSbTe3 which is formed from the combination of two isotopic narrow band gap semiconductors. The initial charge was sealed in evacuated fused silical tubes, heated at 1000 °, held there for 4 days and then slowly cooled to room temperature. The Hall voltage was positive and the Hall coefficient was linear in field up to the highest magnetic field measured and at all temperatures indicating p-type conduction. High resolution microscopy study of the material indicates that the system is a nanostructured composite, rather than a solid solution. Results show that the development of distinct nanostructuring arises from thermo-dynamically driven compositional fluctuations and leads to a very low thermal conductivity which is in accord with results on thermal transport in heterogeneous systems.
