Abstract
Nanoplatelets of Bi2-xSbxTe3 with nominal composition of x = 1.5 are synthesized using hydrothermal methods. The resulting powders are cold pressed and sintered in an evacuated and encapsulated ampoule at 340°C. Scanning electron microscope atomic force microscope, and transmission electron microscope are used to observe the microstructure of nanoplatelets and consolidated Bi0.5Sb1.5Te3. The consolidated Bi0.5Sb1.5Te3 is in fact nanostructured bulk. The power factor and thermal conductivity are 11.6 μW/cm-K2 and 0.37 W/m K at 295 K, respectively. The small thermal conductivity could be largely attributed to its nanostructured nature of the consolidated bulk. The resulting dimensionless figure of merit ZT is 0.93 at 295 K.
