Cobalt oxide is one of the potentials for oxide thermoelectric materials. It shows noticeable electric conductivity, thermal conductivity, ZT value, and Seebeck coefficient. In this work, we measure the thermoelectric power and powder XRD for the polycrystalline rod of Sm doped CCO. There are some behaviour which is correlated between thermal conductivity, Seebeck coefficient, and resistivity. The linearity between thermal conductivity and resistivity of CCO suggests the phonon-charge interaction. It plays an important role on the efficiency of thermoelectric materials.
