Strong electron–phonon coupling influences carrier transport and thermoelectric performances in group-IV/V elemental monolayers

The interactions between electrons and phonons play the key role in determining the carrier transport properties in semiconductors. In this work, comprehensive investigations on full electron–phonon

Temperature-dependent electron-phonon spectral function and the intrinsic resistivity of a metal: A case study of monolayer Ti2N

The transport spectral function of electron-phonon ($e$-ph) interaction in the double $\ensuremath{\delta}$-function approximation (DDFA) is extensively employed to calculate the intrinsic

Thermal conductivity and Lorenz ratio of metals at intermediate temperatures with mode-level first-principles analysis

Electronic and phononic thermal conductivity are involved in the thermal conduction for metals and Wiedemann-Franz law is usually employed to predict them separately. However, Wiedemann-Franz law is

Temperature dependent electron–phonon coupling of Au resolved via lattice dynamics measured with sub-picosecond infrared pulses

The detailed understanding of energy transfer between hot electrons and lattice vibrations at non-cryogenic temperatures relies primarily upon the interpretation of ultrafast pump–probe experiments,

The Variations of Electron and Phonon Contributions to the Thermal Conductivity with Temperature in the Sn–Bi–In–Zn Alternative Lead-Free Solder Alloys

The goal of this paper is to measure the electrical and thermal conductivity variations with temperature in the unidirectional solidified quaternary Sn–Bi–In–Zn lead-free solder alloys for nine

Cooper Pairs Distribution function for bcc Niobium under pressure from first-principles

The Cooper Pairs Distribution function reveals information about the superconductor state through the determination of the spectral regions for Cooper-pairs formation through the calculation of the NCP parameter.

Anomalously Isotropic Electron Transport and Weak Electron-Phonon Interactions in Hexagonal Noble Metals.

The electrical transport properties of typical hexagonal metals are anisotropic because of their anisotropic lattice structures. Unexpectedly, we show that the electron transport properties in



Thermal transport by phonons and electrons in aluminum, silver, and gold from first principles

Mode-dependent phonon and electron transport properties in Al, Ag, and Au are predicted using density functional theory and lattice dynamics calculations. The predicted thermal conductivities,

Mechanisms of nonequilibrium electron-phonon coupling and thermal conductance at interfaces

We study the electron and phonon thermal coupling mechanisms at interfaces between gold films with and without Ti adhesion layers on various substrates via pump-probe time-domain thermoreflectance.

The Electron-Phonon Interaction in Normal Metals

The influence of the electron-phonon many-body renormalization effects on the electron states in normal metals is reviewed. The emphasis is on the electron-phonon mass enhancement parameter λ. The

Effects of Intra- and Interband Transitions on Electron-Phonon Coupling and Electron Heat Capacity After Short-Pulsed Laser Heating

This work considers the effects of intra- and direct interband transitions on electron heat capacity and the electron-phonon coupling factor in metals. In the event of an interband transition, the

Transient thermal and nonthermal electron and phonon relaxation after short-pulsed laser heating of metals

Several dynamic thermal and nonthermal scattering processes affect ultrafast heat transfer in metals after short-pulsed laser heating. Even with decades of measurements of electron-phonon relaxation,

First principles calculation of lattice thermal conductivity of metals considering phonon-phonon and phonon-electron scattering

The effect of phonon-electron (p-e) scattering on lattice thermal conductivity is investigated for Cu, Ag, Au, Al, Pt, and Ni. We evaluate both phonon-phonon (p-p) and p-e scattering rates from first

Limits to thermal transport in nanoscale metal bilayers due to weak electron-phonon coupling in Au and Cu.

Analysis of heat transfer in the bilayer yields the electron-phonon coupling parameter g(T) of Au and Cu, which is consistent with the temperature dependence predicted by the two-temperature model of Kaganov et al.

Electron-phonon interaction via electronic and lattice Wannier functions: superconductivity in boron-doped diamond reexamined.

The calculated phonon self-energy and Eliashberg spectral function show that superconductivity cannot be explained without taking into account the finite-wave-vector Fourier components of the vibrational modes introduced by boron, as well as the breaking of the diamond crystal periodicity induced by doping.
