| Abstract: | ZnO_(1-x)S_x (0≤x≤0.05) bulk samples were fabricated by the solid state reaction method.The effects of S doping on the crystalline structure and thermoelectric properties of ZnO were investigated through measuring the X-ray diffraction (XRD) spectra,electrical conductivity and Seebeck coefficient (thermoelectric power,S) of obtained ZnO samples.The results show that all samples adopt the hexagonal wurtzite structure.At 573 K,the electrical conductivities of ZnO_(1-x)S_x (0＜x≤0.05) (1 723 S·m~(-1)) are much higher than that of neat ZnO (3.02 S·m~(-1)),while the difference in Seebeck coefficient amongst all samples is small.At 1073K,the power factor of ZnO_(0.97)S_(0.03) with a value of 2.5×10~(-4) Wm~(-1)K~(-2) is largest among all samples and is 10 times as large as that of ZnO. |
