Our research group (Thermoelectric Materials and Devices Lab) is specifically interested in bulk thermoelectric materials for Power Generation. Some of our current research activities are listed below: a) High performance materials discovery by engineering electrical and thermal properties: Material systems which are currently being investigated are solid solutions of Mg2Si­Mg2Sn, Mg3Sb2­Mg3Bi2 and ZnSb­CdSb. Solid solutions are known to possess better thermoelectric properties compared to the end members. This is due to the possibility for tuning both the electrical and thermal properties by varying the chemical composition. Our work involves improving TE properties in these solid solutions using a combination of conventional techniques and material specific effects identified from our research. b) Modelling of electronic band structure of thermoelectric materials: Band structure modelling is a topic of interest in TE research as it provides valuable information regarding microscopic material parameters and also for predicting high performance compositions. The modelling work carried out in our group can be subdivided into (i) solution­based approach and (ii) refinement­based optimization approach. We have recently developed a refinement based technique (MBRT) which can handle multiple EBS variables and therefore provide information in TE materials with complex band structures. c) Thermoelectric device fabrication and measu rements: Our research also involves development of suitable electrodes (contacting) and fabrication of TE modules from the in­ house developed materials and their property measurements. We have developed a generic approach for contacting (multi­layer contacting technique) TE materials and demonstrated a conversion efficiency of up to 10% using the high performance materials developed in our group.
