Abstract

In an effort to understand the nature of mass fluctuations introduced when β-K₂Bi₈Se₁₃ is alloyed with K₂Sb₈Se₁₃ we determined the detailed crystal structures of two solid solutions of the type K₂Bi_8-xSb_xSe₁₃ with x=4.0 and x=2.4. The structure is that of β-K₂Bi₈Se₁₃ which is a promising thermoelectric material with low thermal conductivity. The single crystal structures of K_1.49Bi_4.72Sb_3.79Se₁₃ and K_1.49Bi_5.55Sb_2.97Se₁₃ were determined and the Bi/Sb distribution in the structures was examined.
