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…
Probing enhanced electron-phonon coupling in graphene by infrared resonance Raman spectroscopy
Tommaso Venanzi, Lorenzo Graziotto, Francesco Macheda +16
We report on resonance Raman spectroscopy measurements with excitation photon energy down to 1.16 eV on graphene, to study how low-energy carriers interact with lattice vibrations.…
Raman Scattering with infrared excitation resonant with MoSe indirect band gap
Simone Sotgiu, Tommaso Venanzi, Francesco Macheda +4
Resonance Raman scattering, which probes electrons, phonons and their interplay in crystals, is extensively used in two-dimensional materials. Here we investigate Raman modes in Mo…
Electron-phonon interaction and longitudinal-transverse phonon splitting in doped semiconductors
Francesco Macheda, Paolo Barone, Francesco Mauri
We study the effect of doping on the electron-phonon interaction and on the phonon frequencies in doped semiconductors, taking into account the screening in presence of free carrie…
