electron-phonon couplingThe dispersion of acoustic and optical phonons in highly boron-doped diamond has been measured by inelastic X-ray scattering at an energy resolution of 6.4 meV. The sample is doped in the metallic regime and shows superconductivity below 4.2 K (midpoint). The data are ...
It is shown that the anharmonicity of crystal lattice vibrations in light metals such as beryllium,can give rise to a Fermi resonance of optical one-phonon and acoustic two-phononvibrations. New hybridized vibrational states are formed as a result of such a resonance interaction:biphonon and quasi...

We found an intriguing large variation, over similar to 28%, in the acoustic phonon group velocities in this group of materials with similar crystal structures. Our data indicate that the full-width-at-half-maximum of the acoustic phonon peaks is strongly affected by the optical properties and ...
optical phonon scattering dominates and at low temperature acoustic phonon dominate. When the Fermi energy is close to the nodal-line, relaxation due to acoustic phonon is strongly suppressed for all the temperatures above the lattice temperatures. This is because the nodal ring constrains the acousti...
