Observation of strong higher-order lattice anharmonicity in Raman and infrared spectra
© 2020 American Physical Society. The fundamental theory of Raman and infrared (IR) linewidth has been well established as the third-order lattice anharmonicity (three-phonon scattering). In this work, we use both rigorous density functional calculations and Raman experiments to find, surprisingly,...
