- Funded by the Australian Research Council (DE130100310 Discovery & LE120100104 equipment) grants and US department of Energy (S3TEC-EFRC, DE-SC0001299). The project was led by Dr. Sima Aminorroaya, in collaboration with California Institute of Technology, University of New South Wales and Tongji University.
A high thermoelectric efficiency of ~20% was presented, the highest reported efficiency at the time for Pb-chalcogenides with a Te (rare and expensive element) concentration <35 at%. The underlying mechanisms by which the high performance was achieved for heavily doped multiphase materials were described, providing an impetus for a new strategy to design high efficiency thermoelectric materials.
