Abstract
Semiconductor thermoelectric materials are promising candidates for various applications such as power generator, cooler, heat pump, and thermal sensor. In the present work, Al- and Co-doped FeSi<sub>2</sub> thermoelectrics were consolidated by hot pressing at different pressures. For the prepared materials, the phase, the microstructure, and the thermoelectric properties as a function of temperature were characterized. The relationship between the materials factors: density and doping elements, and the thermoelectric parameters: electrical conductivity, thermal conductivity, and the ratio of electrical conductivity to thermal conductivity, is presented. The results show how the performance of thermoelectric FeSi<sub>2</sub> could be affected by controlling materials compositions and processing conditions.
