SnPS: A Promising Infrared Nonlinear Optical Crystal with Strong Non-Resonant Second Harmonic Generation and Phase-matchability
Jingyang He, Seng Huat Lee, Francesco Naccarato +10
High-power infrared laser systems with broadband tunability are of great importance due to their wide range of applications in spectroscopy and free-space communications. These sys…
Assessing the quality of relaxation-time approximations with fully-automated computations of phonon-limited mobilities
Romain Claes, Guillaume Brunin, Matteo Giantomassi +2
The mobility of carriers, as limited by their scattering with phonons, can now routinely be obtained from first-principles electron-phonon coupling calculations. However, so far, m…
Indirect light absorption model for highly strained silicon infrared sensors
Nicolas Roisin, Guillaume Brunin, Gian-Marco Rignanese +2
The optical properties of silicon can be greatly tuned by applying strain and opening new perspectives, particularly in applications where infrared is key. In this work, we use a r…
Boron phosphide as a \emph{p}-type transparent conductor: optical absorption and transport through electron-phonon coupling
Viet-Anh Ha, Bora Karasulu, Ryo Maezono +5
Boron phosphide has recently been identified as a potential high hole mobility transparent conducting material. This promise arises from its low hole effective masses. However, BP…
Phonon-limited electron mobility in Si, GaAs and GaP with exact treatment of dynamical quadrupoles
Guillaume Brunin, Henrique Pereira Coutada Miranda, Matteo Giantomassi +6
We describe a new approach to compute the electron-phonon self-energy and carrier mobilities in semiconductors. Our implementation does not require a localized basis set to interpo…
Electron-Phonon Beyond Fröhlich: Dynamical Quadrupoles in Polar and Covalent Solids
Guillaume Brunin, Henrique Pereira Coutada Miranda, Matteo Giantomassi +6
We include the treatment of quadrupolar fields beyond the Fröhlich interaction in the first-principles electron-phonon vertex in semiconductors. Such quadrupolar fields induce long…
