The GW approximation in electronic structure theory has become a widespread tool for
predicting electronic excitations in chemical compounds and materials. In the realm of …

AlGaN-based materials own direct transition energy bands and wide bandgap and thus can
be used in high-efficiency ultraviolet (UV) emitters and detectors. Over the past two decades …

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 …

Abstract The EPW (Electron-Phonon coupling using Wannier functions) software is a
Fortran90 code that uses density-functional perturbation theory and maximally localized …

The behavior of metals across a broad frequency range from microwave to ultraviolet
frequencies is of interest in plasmonics, nanophotonics, and metamaterials. Depending on …

Multicarrier dynamics play an essential role in quantum dot photophysics and
photochemistry, and they are primarily governed by nonradiative Auger processes. Auger …

Solid‐state lighting (SSL) is now the most efficient source of high color quality white light
ever created. Nevertheless, the blue InGaN light‐emitting diodes (LEDs) that are the light …

Surface plasmons provide a pathway to efficiently absorb and confine light in metallic
nanostructures, thereby bridging photonics to the nano scale. The decay of surface …

We develop a method for calculating the electron-phonon vertex in polar semiconductors
and insulators from first principles. The present formalism generalizes the Fröhlich vertex to …

The electronic ground state of a periodic system is usually described in terms of extended
Bloch orbitals, but an alternative representation in terms of localized “Wannier functions” …
