Raman spectroscopy of femtosecond multi-pulse irradiation of vitreous silica: experiment and simulation
N. S. Shcheblanov, M. E. Povarnitsyn, K. N. Mishchik +1
We report an experimental and numerical study of femtosecond multi-pulse laser-induced densification in vitreous silica (v-SiO2) and its signature in Raman spectra. We compare the…
Boson peak and Ioffe-Regel criterion in amorphous silicon-like materials: the effect of bond directionality
Y. M. Beltukov, C. Fusco, D. A. Parshin +1
The vibrational properties of model amorphous materials are studied by combining complete analysis of the vibration modes, dynamical structure factor and energy diffusivity with ex…
Transverse and longitudinal vibrations in amorphous silicon
Y. M. Beltukov, C. Fusco, A. Tanguy +1
We show that harmonic vibrations in amorphous silicon can be decomposed to transverse and longitudinal components in all frequency range even in the absence of the well defined wav…
Atomistic Simulations of Elastic and Plastic Properties in Amorphous Silicon
Mina Talati, Tristan Albaret, Anne Tanguy
We present here potential dependent mechanical properties of amorphous silicon studied through molecular dynamics (MD) at low temperature. On average, the localization of elementar…
Particle displacements in the elastic deformation of amorphous materials: local fluctuations vs. non-affine field
C. Goldenberg, A. Tanguy, J. -L. Barrat
We study the local disorder in the deformation of amorphous materials by decomposing the particle displacements into a continuous, inhomogeneous field and the corresponding fluctua…
Vibrations of amorphous, nanometric structures: When does continuum theory apply?
J. P. Wittmer, A. Tanguy, J. -L. Barrat +1
Structures involving solid particles of nanometric dimensions play an increasingly important role in material sciences. These structures are often characterized through the vibrati…
