Abstract

BiSb nanoparticles were synthesized by solvothermal method. The synthesized material having a trigonal structure with space group R3m was confirmed through X-ray diffraction pattern. The Williamson-Hall method was employed to analyze the lattice stress and micro-strain produced in the BiSb nanoparticles. On the prepared material surface morphology studies were carried out using HR-SEM with EDXA. UV-visible absorption spectrum shows a wide absorption peak at 287 nm and the estimated band gap value is at E<subscript>g</subscript> = 1.6 eV (from Tauc plot). The values of remanent polarization P<subscript>r</subscript> = 0.156 μC/cm<superscript>2</superscript>, saturation polarization P<subscript>s</subscript> = 0.253 μC/cm<superscript>2</superscript>, and coercive electric field E<subscript>c</subscript> = 13.5 kV/cm obtained from the loop were close to the value. The BiSb nanoparticles exhibit semi-metallic-reported characteristics. This material is useful for thermoelectric power generation applications. [ABSTRACT FROM AUTHOR]
