In this work, we investigate the thermoelectric properties of p and n-type thin films obtained
by cobalt doping of FeS 2. Films were synthesized by direct sulfuration of Co–Fe thin
bilayers at 300° C. It is found that at room temperature (RT), the Seebeck coefficient is
reduced from 80 μV/K to− 70 μV/K when Co concentration is increased and the electrical
resistivity of the films is decreased two orders of magnitude. X-ray diffraction and Raman
measurements point out that Co is replacing Fe into the pyrite lattice and, subsequently is …
