The ternary silver thallium telluride, Ag<SUB>9</SUB>TlTe<SUB>5</SUB>, was reported to exhibit an excellent thermoelectric performance because of its extremely low thermal conductivity. We have studied the effect of the compositional difference on thermoelectric properties of Ag<SUB>9</SUB>TlTe<SUB>5</SUB> by measuring the thermoelectric data on polycrystalline samples with three compositions. A minimal compositional deviation from the stoichiometric Ag<SUB>9</SUB>TlTe<SUB>5</SUB> improved the power factor while the thermal conductivity remained extremely low, leading to an enhancement of the thermoelectric figure of merit.
