Demonstration of a phonon-glass electron-crystal strategy in (Hf,Zr)NiSn half-Heusler thermoelectric materials by alloying

The atomic disorder of Zr/Hf sites in (Hf,Zr)NiSn alloys effectively reduces lattice thermal conductivity and has a negligible effect on electron transport, demonstrating an effective phonon-glass electron-crystal strategy.
