Features of the Microstructure and Thermoelectric Properties of Bi2Te2.7Se0.3 + Fe Composites with Core–Shell Filler Inclusions
Features of the thermoelectric properties and microstructure of composites with a matrix based on Bi2Te2.7Se0.3 and an Fe filler were ascertained. A composition with filler weight content 0.3% Fe has a higher quality factor ZT compared to the Bi2Te2.7Se0.3 matrix. For this composition the maximum value of ZT reaches about 0.75, while for Bi2Te2.7Se0.3 ZT does not exceed about 0.63. So, in a composite of the system Bi2Te2.7Se0.3 + Fe the thermoelectric quality factor can be increased by about 20%.
