Bi₀.₀₄Te₀.₀₆Pb₀.₉₈Se₀.₉₈ is a quaternary lead selenide-based semiconductor alloy doped with bismuth and tellurium, designed to optimize thermoelectric performance through band structure engineering. This material belongs to the lead chalcogenide family—a well-established class for thermoelectric applications—where targeted doping modulates carrier concentration and phonon scattering to improve efficiency in power generation and cooling systems. The specific dopant combination targets enhancement of the dimensionless figure of merit (ZT), making it relevant for waste heat recovery and solid-state thermal management where conventional approaches are inefficient.
