Enhancement of Thermoelectric Figure of Merit in Ternary Silver Thallium Tellurides by Controlling the Carrier Concentration
We tried to improve the thermoelectric figure of merit of a ternary silver thallium telluride, Ag9TlTe5, by controlling the carrier concentration. We studied the effect of deviation from the stoichiometric composition by measuring the thermoelectric properties from room temperature to slightly below the melting temperature of polycrystalline Ag9TlTe5 with different nominal compositions. A minimal compositional deviation of Ag9TlTe5 improved the power factor while the thermal conductivity remained extremely low, leading to an enhancement of the thermoelectric figure of merit
