Atomic-scale structure and thermoelectric properties in medium-entropy PbSnTeSe alloy† Binary IV–VI compounds are typical and promising thermoelectric materials, but their complex solid solutions remain underexplored. Herein, a quaternary PbSnTeSe alloy is screened out from a range of PbSe-SnTe solid solutions through entropy engineering, utilizing its medium entropy to balance phonon and carrier transport properties.
