TLDR
Using the results of self-consistent augmented-plane-wave bandstructure calculations, electron mass enhancement factors and superconducting transition temperatures have been calculated for V, Nb, nbC, TaC, and HfC as mentioned in this paper.Abstract:
Using the results of self-consistent augmented-plane-wave band-structure calculations, electron mass enhancement factors and superconducting transition temperatures have been calculated for V, Nb, NbC, TaC, and HfC. Good agreement with experiment is obtained.read more

The Electron-Phonon Interaction in Normal Metals
TL;DR: The influence of the electron-phonon many-body renormalization effects on the electron states in normal metals is reviewed in this article, where the electron mass enhancement parameter λ is discussed.
Journal ArticleDOI
Electron-phonon coupling in the transition metals: Electronic aspects
TL;DR: In this paper, the electron-phonon coupling parameter was calculated as the product of three factors: the Fermi-energy density of states, $N({E}_{F}), the average of the electron interaction, and an effective inverse lattice force constant.

Dielectric theory of elementary excitations in crystals
TL;DR: In this article, the microscopic theory of dielectric response and its application to elementary excitations is discussed with particular emphasis on periodic solids for which the free-electron description is not valid.

Large-scale 2D PbI2 monolayers: experimental realization and their indirect band-gap related properties
TL;DR: Large-scale PbI2 monolayers and few layers with high crystallinity and a uniform hexagonal shape were synthesized via a facile physical vapour deposition (PVD) method, verified by photoluminescence (PL) spectra, optoelectronic properties, and first principle calculations.

FP-LAPW investigation of electronic structure of TaN and TaC compounds
TL;DR: In this paper, the structural and electronic properties of tantalum compounds were studied by means of accurate first principle total energy calculations using the full-potential linearized augmented plane wave plus local orbitals (FP-LAPW+lo) method.
