Abstract |
The thermoelectric (TE) materials have attracted much attention due to needs for potential renewable energy source. The efficient of thermoelectric devices can be evaluated by the figure of merit , ZT = S2σT/κ , where S is the Seebeck coefficient, σ is the electrical conductivity, T is the absolute temperature and κ is the thermal conductivity.
Among the various kinds of thermoelectric materials, sulfide materials regarded as a promising eco-friendly TE material due to their earth abundant, low-cost and non-toxic elelments. Ternary sulfide Cu2SnS3 has recently attracted attention as an outstanding p-type thermoelectric materials with band gap 0.7-0.9 eV.
In this study, we synthesize metal-doped Cu2SnS3 through solid state reaction. We consolidated metal-doped Cu2SnS3 to pellets with hot press. The crystal structure was investigated with X-ray diffraction and thermoelectric properties by ZEM-3 equipment (Ulvac-Riko) and NETZSCH LFA 457 MicroFlash™. |
