Abstract

Our efforts to improve the thermoelectric properties of β-K₂Bi₈Se₁₃, led to systematic studies of solid solutions of the type β-K₂Bi_8-xSb_xSe₁₃. The charge transport properties and thermal conductivities were studied for selected members of the series. Lattice thermal conductivity decreases due to the mass fluctuation generated in the lattice by the mixed occupation of Sb and Bi atoms. Se excess as a dopant was found to increase the figure-of merit of the solid solutions.
