Abstract
In this study, polycrystalline Cu2SnSe3 (CTSe) has synthesized using the solvothermal method. The characterization done by powder X-Ray diffraction (XRD), Raman-spectroscopic and X-ray photoelectron spectroscopic (XPS) study are confirming the presence of Cu2SnSe3 nanocrystals. The crystalline structure and crystallite size are investigated through an X-ray diffractometer (XRD). The XRD results show that the cubic structure with the crystallite size was found to be 37 nm . Scanning Electron Microscope (SEM) image proved the agglomerated nanosheet-like structure of polycrystalline Cu2SnSe3. Finally, the thermoelectric properties of the Cu2SnSe(3) nanocrystals are investigated at different temperatures in addition calculated physical and transport parameters tabulated for deep understanding of the prepared material.
