Lattice Vibrations and Superconductivity in Layered Structures
In order to estimate the influence of both surface and interface effects on phonon frequencies and superconducting transition temperatures in layered structures, we have calculated the vibrational modes of structures composed of alternating films of heavy and light particles. An interface effectively lowers the vibrational frequencies of the heavy particles and raises those of the light particl...
متن کاملLattice Vibrations – Phonons in Solid State
Phonons are quanta of lattice vibrations. They play an important role in various phenomena seen in solid state. The physics of phonons and phenomena associated with them are explored.
متن کاملThe normal modes of lattice vibrations of ice XI
The vibrational spectrum of ice XI at thermal wavelengths using the CASTEP code, a first-principles simulation method, is investigated. A dual-track approach is constructed to verify the validity for the computational phonon spectrum: collate the simulated spectrum with inelastic neutron scattering experiments and assign the photon scattering peaks according to the calculated normal vibration f...
متن کاملGeometric Theory of Lattice Vibrations and Specific Heat
We discuss, from a geometric standpoint, the specific heat of a solid. This is a classical subject in solid state physics which dates back to a pioneering work by Einstein (1907) and its refinement by Debye (1912). Using a special quantization of crystal lattices and calculating the asymptotic of the integrated density of states at the bottom of the spectrum, we obtain a rigorous derivation of ...
