Keywords: band-structure calculations; energy conversion; Ir3Ge7 type; solid solution; thermoelectric material; Introduction Thermoelectric materials with good efficiency are highly awaited by modern power engineering. Utilizing either the Seebeck or Peltier effects, it is possible to produce electricity

• the low thermal conductivity of the investigated sample, we note that the optimum combination of S and σ for Re3As7−xInx is still to be found. Conclusion Chemical modification of Re3As7 resulted in the formation of the new Re3As7-based solid solution Re3As7−xInx (x ≤ 0.5) with an Ir3Ge7 type of
