  title={Influence of hydrogen on electron-phonon coupling and intrinsic electrical resistivity in zirconium: A first-principles study},
  author={Qicheng Tang and L. A. Svyatkin and Ivan Petrovich Chernov},
  journal={Physical Review B},
The paper presents the first-principle calculation of the electron-phonon coupling and the temperature dependence of the intrinsic electrical resistivity of the zirconium-hydrogen system with various hydrogen concentrations. The nature of the anomalous decrease in the electrical resistivity of the Zr-H system with the increase of hydrogen concentration (at the high concentrations of H/Zr$>$1.5) was studied. It was found that the hydrogen concentration, where the resistivity starts to decrease…

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
A first principles investigation of the hydrogen-strain synergy on the formation and phase transition of hydrides in zirconium
Abstract The precipitation of hydrides phases is known to be a source of embrittlement in zirconium and its alloys. In the present work, the effects of hydrogen (H) in the bulk of Zirconium (Zr)
Thermal scattering law data generation for hydrogen bound in zirconium hydride based on the phonon density of states from first-principles calculations
Abstract The thermal neutron scattering cross sections of zirconium hydride (ZrHx) is heavily affected by its lattice structure which can be represented by phonon density of states (DOS). In the past


Electron-phonon interactions from first principles
This article reviews the theory of electron-phonon interactions in solids from the point of view of ab-initio calculations. While the electron-phonon interaction has been studied for almost a
Electronic properties and electron-phonon coupling in zirconium and niobium hydrides
The electronic structure of the two 4d transition-metal cubic dihydrides ZrH/sub 2/ and NbH/sub 2/ is investigated by means of an augmented-plane-wave (APW) band-structure calculation. The position
High-pressure hydrogen sulfide from first principles: a strongly anharmonic phonon-mediated superconductor.
First-principles calculations are used to study structural, vibrational, and superconducting properties of H2S and H3S and show that High-pressure hydrogen sulfide is a strongly anharmonic superconductor.
Electron-Phonon Effects in the Infrared Properties of Metals
Electron-phonon contributions to the infrared absorption in metals are examined from two points of view. First, "golden-rule" calculations are given for normal metals and superconductors which
