Abstract
We report fabrication of compacted Bi0.5Sb1.5Te 3 nanoplatelets using hydrothermal methods followed by cold pressing and sintering in an evacuated ampoule at various temperature of 300-380 °C. The compacted Bi0.5Sb1.5Te3 sintered at 340 °C has the highest power factor of 11.6 μW/cmK2 and its thermal conductivity is 0.37 W/mK at 295 K, which is very low as compared to the typical value of 1 W/mK. The resulting dimensionless figure of merit ZT is 0.93 at 295 K.
