Experimental survey of dopants in Zn13Sb10 thermoelectric material

This work explores a variety of dopant incorporations into the Zn13Sb10 thermoelectric material synthesized from the stoichiometric composition by slow cooling. The experimental results revealed the preference for dopant atoms that can adopt a tetrahedral coordination environment of the Zn site. Incorporations of the dopants restrict the movement of Zn atoms, as evident from the suppressed α/α’ – β phase transitions. Incorporations affect both …
