Effect of thermal annealing on structural, electrical and thermoelectric properties of p-type Bi0.5Sb1.5Te3
The present study reports the effect of annealing on the phase, structure and thermoelectric properties of Bi0.5Sb1.5Te3 prepared by melt quenching method. The extracted ingots were pelletized followed by annealing at 400°C. Microstructure of the as-extracted pellets contained Te-rich inclusions which disappeared on annealing due to Te sublimation. The Seebeck coefficient enhanced about two times on annealing due to significant increase in hole mobility. The combination of melt quenching followed by annealing is one of the effective ways to synthesize the high-performance BiSbTe-based materials.The present study reports the effect of annealing on the phase, structure and thermoelectric properties of Bi0.5Sb1.5Te3 prepared by melt quenching method.
