▎ 摘　　要

The primary purpose of this study was to observe the effects of graphene doping on the structure and the physical properties of n-type thermoelectric materials. Structural characterizations of the produced materials were measured by X-ray diffraction (XRD), scanning electron microscope (SEM), energy-dispersive X-ray spectroscopy (EDX), and Fourier-transform infrared spectroscopy (FTIR). Temperature-dependent thermal conductivity and the Seebeck coefficient measurements were applied via physical properties measurement system (PPMS). After XRD analyses, the diffractograms showed that the produced materials had crystalline forms. With respect to observing SEM micrographs, the homogenization of the samples usually increased with graphene doping. The results of temperature-dependent thermal conductivity and the Seebeck coefficient measurements revealed that graphene doping had a positive influence on both values.
