Beyond the one-dimensional configuration coordinate model of photoluminescence
Yongchao Jia, Samuel Poncé, Anna Miglio +2
The one-dimensional configuration coordinate model (1D-CCM) is widely used for the analysis of photoluminescence in molecules and doped solids, and relies on a linear combination o…
Electron-plasmon and electron-phonon satellites in the angle-resolved photoelectron spectra of n-doped anatase TiO2
Fabio Caruso, Carla Verdi, Samuel Poncé +1
We develop a first-principles approach based on many-body perturbation theory to investigate the effects of the interaction between electrons and carrier plasmons on the electronic…
First-principles Study of the Luminescence of Eu2+-doped Phosphors
Yongchao Jia, Anna Miglio, Samuel Poncé +2
The luminescence of fifteen representative Eu-doped phosphors used for white-LED and scintillation applications is studied through a Constrained Density Functional Theory. T…
First-principles study of Ce doped lanthanum silicate nitride phosphors: Neutral excitation, Stokes shift, and luminescent center identification
Yongchao Jia, Anna Miglio, Samuel Poncé +2
We study from first principles two lanthanum silicate nitride compounds, LaSiN and LaSiN, pristine as well as doped with Ce ion, in view of ex…
Precise effective masses from density functional perturbation theory
Jonathan Laflamme Janssen, Yannick Gillet, Samuel Poncé +3
The knowledge of effective masses is a key ingredient to analyze numerous properties of semiconductors, like carrier mobilities, (magneto-)transport properties, or band extrema cha…
Temperature dependence of the electronic structure of semiconductors and insulators
Samuel Poncé, Yannick Gillet, Jonathan Laflamme Janssen +3
The renormalization of electronic eigenenergies due to electron-phonon coupling is sizable in many materials with light atoms. This effect, often neglected in ab-initio calculation…
