Misfit layer superconductors, tuneable bulk heterostructures with strong 2D effects
Tomas Samuely, Martin Gmitra, Tristan Cren +2
Atomically thin layered materials are systems with zero limit bulk-to-surface ratio. Their physical properties are determined by two-dimensionality and strongly affected by interfa…
Light-Induced Nonthermal Phase Transition to the Topological Crystalline Insulator State in SnSe
Stefano Mocatti, Giovanni Marini, Matteo Calandra
Femtosecond pulses have been used to reveal hidden broken symmetry states and induce transitions to metastable states. However, these states are mostly transient and disappear afte…
Theory of infrared double-resonance Raman spectrum in graphene: the role of the zone-boundary electron-phonon enhancement
Lorenzo Graziotto, Francesco Macheda, Thibault Sohier +2
We theoretically investigate the double-resonance Raman spectrum of monolayer graphene down to infrared laser excitation energies. By using first-principles density functional theo…
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…
Electronic structure and lattice dynamics of 1T-VSe: origin of the 3D-CDW
Josu Diego, D. Subires, A. H. Said +21
In order to characterize in detail the charge density wave (CDW) transition of 1-VSe, its electronic structure and lattice dynamics are comprehensively studied by means of x…
Electron-phonon driven charge density wave in CuTe
Marco Campetella, Giovanni Marini, Jianqiang Sky Zhou +1
The compound CuTe (vulcanite) undergoes a quasi one dimensional charge density wave (CDW) at K with a periodicity. The mechanism at its…
