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…
Metallic crossover through the tilt-free transition in LaNiO at high pressure and temperature
Bastien Michon, Yingpeng Yu, Beatrice D'Alò +8
LaNiO, a bilayer nickelate with Ruddlesden-Popper structure, undergoes a pressure-induced structural transition from a tilted Amam phase to an untilted Fmmm (or I4/mmm)…
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.…
Tuning Ultra-Narrow Direct Bandgap in alpha-Sn Nanocrystals: A CMOS-Compatible Approach for THz Applications
Tiziano Bertoli, Elena Stellino, Francesco Minati +14
alpha-Sn has recently been attracting significant interest due to its unique electronic properties. However, this allotrope of Sn is stable only below 13 °C and alternative option…
