Doubling the ZT record of TiS2-based thermoelectrics by incorporation of ionized impurity scattering

Abstract

We report hereby the high performance of TiS2-based nanocomposites incorporating ionized impurity (nano-AgSnSe2) for electron scattering, which syergistically caused the improvement in electrical conductivity and Seebeck coefficient, and the reduction of lattice thermal conductivity. As a result, a maximum ZT ~0.8 at 700 K has been obtained as a renewed record.
