The InSb nanoinclusions formedin situat the grain boundaries of FeSb2.2Te0.8mitigates 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.
