    the energy flow from electrons to phonons dominates over the energy backflow due to reabsorption of nonequilibrium phonons by electrons; however, while the energy backflow in YBCO can be neglected because of the very large ratio Cp/Ce = 38, in NbN it constitutes a non-negligible 15% (Cp/Ce = ) of direct electron–phonon energy relaxation.

Similarly, experimentalists studying phonons at low temperatures have relied heavily on supercon­ ductors as sources and detectors. To a large extent this symbiotic relationship has developed with a general mutual awareness; however, to our knowledge these subjects have never.

The physics of nonequilibrium electrons and phonons in semiconductors is an important branch of fundamental physics that has many practical applications, especially in the development of ultrafast and ultrasmall semiconductor devices. This volume is devoted to different trends in the field which are presently at the forefront of research.

to superconductors by Eliashberg. [12] A similar approach was given by Nambu. [13] The theories are accurate to terms of order (m/M) 1/2, where m is the mass of the electron and M the mass of the ion, and so give quite accurate quantitative accounts of the properties of both normal metals and super-conductors.

Introduction. Size effects and large deviation from equilibrium often characterize transport of electrons and phonons in nanostructures. In very thin films with a thickness less than one electron mean free path (MFP), for example, electrons going through the film experience little or no scattering, and the electric current is controlled by the barrier heights of the heterojunction, as.

Effect of nonequilibrium phonons on superconducting states with two coexisting energy gaps Article (PDF Available) January with 6 Reads How we measure 'reads'.

for electron-phonon mediated superconductors, we work with the fully dressed phonons, extracted from experi-ment, and hence we do not renormalize the phonons at all, only the electrons are dressed self-consistently by the phonons.

Such an approach might begin to fail in nonequilibrium if a significant amount of energy is trans. The work provides new insights on the specific phonon branches involved in the nonequilibrium heat dissipation from the high-energy Cu–O bond stretching “hot” phonons to the lowest-energy acoustic phonons with correlated atomic motion along the crystal directions and.

tween electrons and the crystal lattice of a superconductor. Quantized lattice vibrations, or phonons, are exchanged among the electrons in a superconductor. It is often more useful to characterize an electron in a conducting material as a so-called quasiparticle, which can have.

The dependence of the superconducting gap of a thin superconducting film under irradiation by a UHF field is investigated for different values of the amplitude and frequency of the electromagnetic field and arbitrary temperatures.

It is shown that the maximal stimulation of superconductivity does not exceed several percent. The distribution functions of nonequilibrium quasiparticles are found. Phonons in crystals and electromagnetic photons are both characterized by zero spins and P = +1, whereas electrons and protons are particles of spin and.

In general, elementary particles are characterized by spins, where n is either an even or odd integer, corresponding to the exchange operator of +1 or, respectively, which can be applied to.

Interpretation in terms of electronic structure, chemical purity, crystal structure, and crystal perfection is emphasized as a tool for electrons and phonons ziman investigation but detailed discussion of individual means or alloys is avoided.

between electrons, holes and phonons. Another advanced con-cept approach is multi-exciton generation (MEG) [, ], in which energetic electrons (holes) generated by high energy photons have sufficient excess energy to create an additional electron hole pair before relaxing in energy through compet-ing electron–phonon interactions.
