Phonons are quantized units of lattice vibrations or collective atomic motions in a solid. They can be thought of as particles representing the vibrational energy of the crystal lattice. Phonons can influence the dynamics of excitons by providing channels for energy relaxation or scattering processes....
Lattice vibrations and phonon-plasmon coupling in {R}aman spectra of extit{p}-type {In_{0.53}Ga_{0.47}As}Mintairov, A MTemkin, H
In summary, phonons are quantized lattice vibrations characterized by traveling waves of the form exp(ikr) satisfying periodic boundary conditions. They are also known as normal modes of vibration, which can include standing waves in which all atoms move in phase with each other, or more general...
Electron transport hinges on electronic structure of a material and various scattering events. Among these, scattering by phonons stands out as one of the most fundamental mechanisms, as it occurs even in pristine single crystals. But only recently have advances in the development of accurate first-...

Anharmonic lattice vibrations play pivotal roles in the thermal dynamics in condense matters and affect how the atoms interact and conduct heat. An in-depth understanding of the microscopic mechanism of phonon anharmonicity in condensed systems is critical for developing better functional and energy mate...

The properties of these vibrations are strongly affectednby the displacement of ions which occurs when the lattice temperaturenapproaches the ferroelectric phase transition temperature. Thendielectric properties of LiTaO3 and LiNbO3 can bendescribed by modelling these modes with a microscopic vibrationalnpo...
To understand the material properties and the distinct phenomena in the microscopic scale, such as their lattice dynamics require robust and accurate computational tools. For ordered crystals, the theory of lattice vibrations has been set up on a rigorous basis. However, for disordered lattice, no ...
