- The JNCASR – Bengaluru (the Jawaharlal Nehru Centre for Advanced Scientific Research), have developed a cutting-edge material capable of converting waste heat into energy with unprecedented efficiency.
- The team has synthesised a novel thermoelectric material by introducing twisted layers in ferecrystals, a unique class of misfit layered compounds.
- The material, based on tin selenide (SnSe), exhibits a thermoelectric figure of the merit of 2.3, the highest reported for n-type materials.
- With about 65 per cent of all the utilised energy being lost as heat in nature, thermoelectric materials offer a sustainable solution by converting waste heat into electricity without emitting harmful gases like CO2.
- Ferecrystals are a subclass of misfit layered compounds (MLCs), which are 2D superlattices made of alternating layers of different structures.
