Resonantly-enhanced Raman response in graphene-capped bismuthene on SiC
Lukas Gehrig, Cedric Schmitt, Erica Fragomeni +15
Two-dimensional quantum spin Hall insulators based on atomic monolayers offer a promising route toward dissipationless electronics, yet their practical use is often limited by envi…
Infrared resonance Raman of bilayer graphene: signatures of massive fermions and band structure on the 2D peak
Lorenzo Graziotto, Francesco Macheda, Tommaso Venanzi +14
Few-layer graphene possesses low-energy carriers which behave as massive fermions, exhibiting intriguing properties in both transport and light scattering experiments. Lowering the…
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…
Photoluminescence dynamics in few-layer InSe
Tommaso Venanzi, Himani Arora, Stephan Winnerl +10
We study the optical properties of thin flakes of InSe encapsulated in hBN. More specifically, we investigate the photoluminescence (PL) emission and its dependence on sample thick…
