Ultralow Thermal Conductivity and High Thermopower in a New Family of Zintl Antimonides Ca10MSb9 (M = Ga, In, Mn, Zn) with Complex Structures and Heavy Disorder

A new family of Zintl antimonides with the approximate composition Ca10MSb9 (M = Ga, In, Mn, Zn) has been obtained via two synthetic approaches: (1) using Sb as a flux and (2) using the conventiona...
