Spontaneous emission of light by non-equilibrium phonons
J. Plo, P. Valvin, M. Moret +8
When a system is brought out of equilibrium by an external excitation, its relaxation to thermodynamic equilibrium generates phonons. These non-equilibrium phonons degrade via casc…
Coupled dynamical Boltzmann transport equations with long-range electron-phonon and electron-electron interactions in 2D materials
Francesco Macheda, Thibault Sohier
We study the interplay between long-range electron-phonon and electron-electron interactions in electrostatically doped two-dimensional semiconductors, including interlayer couplin…
Electronic transport in BN-encasulated graphene limited by remote phonon scattering
Khalid Dinar, Francesco Macheda, Alberto Guandalini +6
We study the impact of BN's phonons on the electrical resistivity of hBN-encapsulated graphene. While encapsulation yields high-mobility devices, the surrounding BN itself introduc…
Ab-initio Van der Waals electrodynamics: polaritons and electron scattering from plasmons and phonons in BN-capped graphene
Francesco Macheda, Francesco Mauri, Thibault Sohier
Plasmons and polar phonons are elementary electrodynamic excitations of matter. In 2d and at long wavelengths, they couple to light and act as the system polaritons. They also dict…
Electron-phonon interaction and phonons in 2d doped semiconductors
Francesco Macheda, Thibault Sohier, Paolo Barone +1
Electron-phonon interaction and phonon frequencies of doped polar semiconductors are sensitive to long-range Coulomb forces and can be strongly affected by screening effects of fre…
