ThezTof Yb14MnSb11is improved by the introduction of a light rare earth element, RE3+(RE = Pr, Sm) with partially filled f-levels. The carrier concentration is reduced upon substituting RE3+for Yb2+, adding one electron to the system and improving thezTvalues 30–40% over that of the pristine material.
