Abstract
We report on thermoelectric properties of n-type nanostructured bulk Si0.8Ge0.2 with the addition of FeSi2 prepared via two sintering routes: the conventional spark plasma sintering method and a direct current pressing technique. The thermal conductivity, the electrical conductivity, and the Seebeck coefficient have been determined over the temperature range from 25°C to 900°C in a helium atmosphere. The highest ZT value for the multiphase nanostructured composite was reached at ∼0.6 at 900°C. Embedding of 10 at.% FeSi2 phase had a positive impact on thermal properties but dramatically affected the power factor, which eventually resulted in a drop of the thermoelectric efficiency. It was also shown that the orthorhombic β-FeSi2 phase transforms to a tetragonal α-FeSi2 phase during high temperature sintering.
