Apr 8, 2025 · In this work, we experimentally and computationally investigate the nature of phonon scattering and thermal transport in a series of single and multi-cation rare earth …

April 23, 2004 Scattering Rate Calculations Overview Step 1: Determine Scattering Potential Step 2: Calculate Matrix Elements Step 3: Calculate State-State Transition Rates Step 4: Calculate …

Mar 26, 2025 · The change in mass and induced strain effects at the point defect sites lead to phonon scattering, which, in turn, reduces thermal conductivity. The scattering mechanism of …

This can be understood based on strong anharmonicity and short intrinsic phonon mean-free-paths in of PbTe. Jury is still out on the question of new physics in rough nanowires. But we …

Sep 24, 2024 · Our study gives insights into the high-order four-phonon effect in solids, which has guiding significance for designing thermal management materials.

Phonons can scatter through several mechanisms as they travel through the material. These scattering mechanisms are: Umklapp phonon-phonon scattering, phonon-impurity scattering, …

Selection rules act to restrict the intrinsic anharmonic interactions between phonons in all crystals. Yet their influence on phonon propagation is hidden in most materials and so, hard to …

Phonon scattering refers to the process by which phonons, which are quantized vibrations of atoms in a crystal lattice, are scattered by other phonons, defects, impurities, and boundaries.
