Second-Order Raman Scattering in Exfoliated Black Phosphorus
Alexandre Favron, Félix Antoine Goudreault, Vincent Gosselin +7
Second-order Raman scattering has been extensively studied in carbon-based nanomaterials, \emph{e.g.} nanotube and graphene, because it activates normally forbidden Raman modes tha…
Effect of spin-orbit coupling on the zero-point renormalization of the electronic band gap in cubic materials: First-principles calculations and generalized Fröhlich model
Véronique Brousseau-Couture, Xavier Gonze, Michel Côté
The electronic structure of semiconductors and insulators is affected by ionic motion through electron-phonon interaction, yielding temperature-dependent band gap energies and zero…
Zero-point lattice expansion and band gap renormalization: Grüneisen approach versus free energy minimization
Véronique Brousseau-Couture, Émile Godbout, Xavier Gonze +1
The zero-point lattice expansion (ZPLE) is a small variation of the lattice parameters induced by the presence of phonons in a material compared to the static lattice picture. It c…
Predominance of non-adiabatic effects in zero-point renormalization of the electronic band gap
Anna Miglio, Véronique Brousseau-Couture, Emile Godbout +6
Electronic and optical properties of materials are affected by atomic motion through the electron-phonon interaction: not only band gaps change with temperature, but even at absolu…
Unconventional field induced phases in a quantum magnet formed by free radical tetramers
Andres Saul, Nicolas Gauthier, Reza Moosavi Askari +11
We report experimental and theoretical studies on the magnetic and thermodynamic properties of NIT-2Py, a free radical-based organic magnet. From magnetization and specific heat me…
Phonon-Induced Transparency in Functionalized Single Layer Graphene
Bruno Rousseau, François Lapointe, Minh Nguyen +8
Herein, intervalley scattering is exploited to account for anomalous antiresonances in the infrared spectra of doped and disordered single layer graphene. We present infrared spect…
