Na0.02Pb0.98Te0.85Se0.15 is a lead telluride-based compound semiconductor with sodium and selenium dopants, belonging to the IV-VI narrow-bandgap ceramic family commonly studied for thermoelectric applications. This is primarily a research material rather than a widely commercialized product; it represents compositions being investigated to optimize the thermoelectric figure of merit through band structure engineering and phonon scattering control. The material is chosen by researchers developing thermoelectric generators and coolers because strategic doping and alloying in the PbTe system can yield favorable coupling between electrical conductivity and thermal properties needed for waste heat recovery or solid-state cooling.
