  • Vacancies are traditionally considered to play a role of phonon-defect scattering. Here, the authors show that vacancies can induce phonon softening, enhance phonon anharmonicity, and cause a dramatic reduction in the lattice thermal conductivity.

  • Chemical doping plays an important role in tuning carrier concentration of materials, but its influence on other aspects of electrical properties is less known. Here, the authors find that chemical doping brings strong screening effects to ionized impurities, grain boundary, and polar optical phonon scattering.
