High temperature thermoelectric properties of Czochralski-pulled Ba8Ga16Ge30
High temperature thermoelectric properties have been measured on a Czochralski pulled Ba8Ga16Ge30 crystal. Complete transport properties obtained in the temperature range from 273K to 1150K. The physical properties are reproducible even after thermal cycling. The Seebeck coefficient reveals the sample to be an n-type conductor with a maximum value of -148 muV/K at 1073K. The electrical resistivity shows the characteristics of a heavily doped semi conductor, and it goes through a maximum at 1073 K with a value of 1.7 mOmega-cm. The thermal conductivity goes through a minimum of 1.25 W/m-K around 900K, and ZT reaches a maximum of 0.9 at 1000 K
