<jats:title>Abstract</jats:title>
<jats:p>In this work, we elucidated the electronic structure and thermoelectric properties of intermetallic <jats:italic>X</jats:italic>Si (<jats:italic>X</jats:italic> = Co, Rh) compounds. By combining first-principles calculations and the Boltzmann equation within electron–phonon average approximation, thermoelectric properties of <jats:italic>X</jats:italic>Si are well reproduced compared to experimental observations. We found that the considerable Seebeck coefficient and low electrical resistivity give <jats:italic>X</jats:italic>Si a large power factor, which has the potential for thermoelectric applications. We also discussed the electron mean free paths, a possible factor affecting electrical conductivity when using the nanostructuring approach to optimize the thermoelectric performance.</jats:p>
