Description We have been able at this early stage of the research that the modelling work can accurately describe the transport properties of a sulphide thermoelectric compound (Cu3SbS4). The modelling work guided the optimisation of doping. We then made materials with a range of Ge doping and measured their properties to validate the modelling work.

We have continued to collaborate and apply the experimental and theoretical techniques to investigate the addition of Sn to explore the structural details of this system and to optimise the thermoelectric performance.
Exploitation Route We have published a paper on our early results. We believe this will be of interest and use to the modelling and thermoelectrics communities.

We will shortly submit our work on the Sn substituted compounds.

The work on sulphide thermoelectrics has attracted interest by European Thermodynamics. Using the knowledge we gained on sulphide thermoelectrics in the DEFCOM project, we are exploring the performance of bismuth sulphide related compounds.
