Thermoelectric properties of quaternary BixSbyPbzSe3 single crystals

Original language description

Single crystals of quaternary system based on Bi2Se3 co-doped with Sb and Pb were prepared using the Bridgman technique. Samples with varying content of Pb and Sb were characterized by measurements of the lattice parameters, electrical resistivity, Hallcoefficient, Seebeck coefficient and thermal conductivity. Atomic emission spectroscopy was used to find the concentration profiles of Sb and Pb along the single-crystalline ingots. The measurements indicate that by incorporating Pb and Sb in Bi2Se3 onelowers the concentration of free electrons and changes the character of electrical conductivity from n-type to p-type. This effect is explained in terms of point defects. Further, the evolution of the figure of merit is presented as a function of the impurity content.
