Scientists have found a new Lead (Pb) free material which can efficiently convert waste heat to power our small home equipment and automobiles.
- Scientists from Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR) led by Prof. Kanishka Biswas have identified a lead-free material called Cadmium (Cd) doped Silver Antimony Telluride (AgSbTe2) which can efficiently allow recovery of electricity from ‘waste heat’ marking a paradigm shift in the thermoelectric puzzle.
- Prof. Kanishka Biswas and his group doped (internally introduced) Silver Antimony Telluride with Cadmium (Cd) and used an advanced electron microscopy technique to visualize the resultant ordering of atoms in nanometer scale.
- The nanometer-scale atomic ordering scatters phonons that carries heat in a solid and enhances electrical transport by delocalizing the electronic state in the material.
- They have reported this major breakthrough in the journal Science.
