FEATURES IN MICROSTRUCTURE AND THERMOELECTRIC PROPERTIES OF THE COMPOSITES Bi2Te2,7Se0,3+Fe WITH FILLER INCLUSIONS OF CORE-SHELL TYPE

Year: 2023

Type: article

Abstract: Purpose of this work is to establish the features in the microstructure and thermoelectric properties of composites consisting of Bi2Te2.7Se0.3-based matrix and a Fe filler. The composition with a filler content of 0.3 wt. % Fe has a higher thermolectric figure of merit as compared to the Bi2Te2.7Se0.3 matrix. For this composition, the maximum value of ZT reaches ~0.75, while for Bi2Te2.7Se0.3 ZT does not exceed ~0.63. Thus, in the composite of the Bi2Te2.7Se0.3 + Fe system, the thermoelectric figure of merit can be increased by about 20 %.
