Full TextAbstract
In this work, Bi2Te2.7Se0.3, Bi2Te2.1Se0.9 and Bi2Te1.5Se1.5 powders were synthesized by a hydrothermal method, by using BiCl3,Te, and Se powders as starting materials together with NaBH4, NaOH and EDTA as the reductant, PH-value controller and additive, respectively. Then 100 nm thin films of powders fabricated by physical vapor deposition(PVD) . Morphology of the prepared samples were investigated by X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM) . Samples were characterized with FTIR spectroscopy. The hexagonal structure was observed for all of powders and thin films from the XRD results. The crystallite size of 8 to 20 nm were obtained using Scherrer equation . The thermoelectric measurement was carried out on the thin film samples .
