AbstractWe present the synthesis and structure of the new chalcogenide compounds, Rb0.5Bi1.83Te3, APb2Bi3Te7 (A = Cs, Rb), K1.25Pb3.50Bi7.25Se15 and A1+xPb4−2xSb7+xSe15 (A = K, Rb). The layered structures of the first two telluride compounds are related to each other in a very interesting fashion. These compounds are n-type metallic conductors and solid solutions with Se and Sb have also been synthesized. K1.25Pb3.50Bi7.25Se15 and its Sb analogs have a complex three-dimensional structure composed of NaCl- and Bi2Te3-type building units. The thermal stability, melting behavior, electrical conductivity and thermopower of these compounds are reported.

ABSTRACTOur efforts to improve the thermoelectric properties of β-K2Bi8Se13, led to systematic studies of solid solutions of the type β-K2Bi8−xSbxSe13. 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.

Effective Masses

Valence band dispersions of single-crystalline SnS1-xSex solid solutions were observed by angle-resolved photoemission spectroscopy (ARPES). The hole effective masses, crucial factors in determining thermoelectric properties, were directly evaluated. They decrease...
