· JVASP-110279· Bi2Te4Pb

Bi2Te4Pb is a layered bismuth telluride-based ceramic compound belonging to the thermoelectric materials family. This material is primarily investigated in research contexts for thermoelectric energy conversion applications, where its layered crystal structure and composition make it a candidate for solid-state cooling and waste heat recovery devices. The lead-doped bismuth telluride system represents an experimental optimization of the widely-used Bi2Te3 thermoelectric platform, with potential advantages in tuning electronic and thermal transport properties for next-generation thermoelectric generators and Peltier coolers.
