The InSb nanoinclusions formed in situ at the grain boundaries of FeSb2.2Te0.8 mitigates the mobility degradation while the added grain boundaries effectively scatter heat-carrying phonons. This novel “electron-channel phonon-barrier” nanocompositing approach opens a new route to design high performance thermoelectric materials.
