<b>Hierarchical scattering</b> is suggested as an effective strategy to enhance the figure of merit <i>zT</i> of heavy-band thermoelectric materials. Heavy-band FeNbSb half-Heusler system with intrinsically low carrier mean free path is demonstrated as a paradigm. An enhanced <i>zT</i> of 1.34 is obtained at 1150 K for the Fe<sub>1.05</sub>Nb<sub>0.75</sub>Ti<sub>0.25</sub>Sb compound with intentionally designed hierarchical scattering centers. ...[more]
