Vibrational dynamics of non-crystalline solids
Giacomo Baldi, Aldo Fontana, Giulio Monaco
The boson peak (BP) is an excess of vibrational states over the Debye law appearing at terahertz frequencies. It is found in all glasses and marks the crossover between the long-wa…
Effect of Polymerization on the Boson Peak, from the Liquid to Glassy Phase
S. Caponi, S. Corezzi, D. Fioretto +3
Raman scattering measurements are used to follow the modification of the vibrational density of states in a reactive epoxy{amine mixture during isothermal polymerization. Combining…
Neutron scattering study of the vibrations in vitreous silica and germania
E. Fabiani, A. Fontana, U. Buchenau
The incoherent approximation for the determination of the vibrational density of states of glasses from inelastic neutron or x-ray scattering data is extended to treat the coherent…
Evidence of anomalous dispersion of the generalized sound velocity in glasses
B. Ruzicka, T. Scopigno, S. Caponi +7
The dynamic structure factor, S(Q,w), of vitreous silica, has been measured by inelastic X-ray scattering in the exchanged wavevector (Q) region Q=4-16.5 nm-1 and up to energies hw…
The nature of the short wavelength excitations in vitreous silica: X-Rays Brillouin scattering study
O. Pilla, A. Cunsolo, A. Fontana +6
The dynamical structure factor (S(Q,E)) of vitreous silica has been measured by Inelastic X-ray Scattering varying the exchanged wavevector (Q) at fixed exchanged energy (E) - an e…
