Materials scientists can regulate the configurational entropy of a material by introducing different atomic species to tune phase composition and extend the performance optimization space. In a new report now on Science, Binbin Jang et al. used an n-type lead selenide (PbSe)-based high-entropy material formed by entropy-driven structural stabilization. The largely distorted lattices in the high-entropy system caused unusual shear strains to provide strong phonon scattering to lower lattice thermal conductivity. The work presents a new paradigm to improve thermoelectric performance for high-entropy thermoelectric materials using entropy engineering.&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\n Click here for original story, <a href=\"https:\/\/phys.org\/news\/2021-03-high-entropy-stabilized-chalcogenides-high-thermoelectric.html\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">High-entropy-stabilized chalcogenides with high thermoelectric performance<\/a>&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\nSource: Phys.org&#013;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Thermoelectric technology can generate electricity from waste heat, although their performance can result in a bottleneck for wider applications.
