Thermal treatment effects on PMN-0.4PT/Fe multiferroic heterostructures
Deepak Dagur, Alice Margherita Finardi, Vincent Polewczyk +10
Multiferroic heterostructures have gained in recent years a renewed role in spintronic applications due to their possibility in controlling the magnetic properties via interfacial…
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.…
Possible realization of a phononic tsunami in a wedge-shaped sample
Yuriy Yerin, Andrey Varlamov, Claudia Fasolato +3
Exploiting the theory of solitons in a nonlinear elastic medium we predict a novel phenomenon called a phononic tsunami, which is characterized by the dramatic increase of the loca…
Superradiant Thomson scattering from graphite in the extreme ultraviolet
C. Fasolato, E. Stellino, E. Principi +6
We study the Thomson scattering from highly oriented pyrolitic graphite excited by the extreme ultraviolet, coherent pulses of FERMI free electron laser (FEL). An apparent nonlinea…
Advanced Raman spectroscopy detection of oxidative damage in nucleic acid bases: probing chemical changes and intermolecular interactions in guanosine at ultralow concentration
Francesca Ripanti, Claudia Fasolato, Flavia Mazzarda +8
DNA/RNA synthesis precursors are especially vulnerable to damage induced by reactive oxygen species occurring following oxidative stress. Guanosine triphosphates are the prevalent…
DNA-functionalized gold nanoparticle assemblies for Surface Enhanced Raman Scattering
D. Caprara, F. Ripanti, A. Capocefalo +5
The programmable assembly of DNA strands is a promising tool for building tailored bottom-up nanostructures. Here, we present a plasmonic nanosystem obtained by the base-pairing me…
Temperature dependence of the surface plasmon resonance in small electron gas fragments, self consistent field approximation
Claudia Fasolato, Francesco Sacchetti, Pietro Tozzi +1
The temperature dependence of the surface plasmon resonance in small metal spheres is calculated using an electron gas model within the Random Phase Approximation. The calculation…
Raman spectroscopy of graphene under ultrafast laser excitation
C. Ferrante, A. Virga, L. Benfatto +11
The equilibrium optical phonons of graphene are well characterized in terms of anharmonicity and electron-phonon interactions, however their non-equilibrium properties in the prese…
