Electronic Structure and Thermoelectric Properties of the Thioantimonate
FePb4Sb6S14. — The title compound is synthesized by annealing stoichiometric mix22- 012 tures
of the elements at 600 °C and characterized by LMTO band structure calculations
and electrical conductivity measurements. The compound is a semiconductor and exhibits high thermopower, however, the low electrical conductivity inhibits its use in
thermoelectric applications. Chemical doping with Co and Sn enhances the electrical
conductivity to some extent. — (DERAKHSHAN, S.; ASSOUD, A.; SOHEILNIA,
