Bond angle distribution in amorphous germania and silica
The distribution of Ge-O-Ge and Si-O-Si bond angles α in amorphous germania and silica is re-determined on the basis of diffraction experiments. The bond angle α joining adjacent tetrahedra is the central parameter of any continuous random network description (CRN) of these glasses. New high energy photon diffraction experiments on amorphous germania (at photon energies of 97 and 149 keV) are p...
متن کاملThermal conductivity accumulation in amorphous silica and amorphous silicon
We predict the properties of the propagating and nonpropagating vibrational modes in amorphous silica (a-SiO2) and amorphous silicon (a-Si) and, from them, thermal conductivity accumulation functions. The calculations are performed using molecular dynamics simulations, lattice dynamics calculations, and theoretical models. For a-SiO2, the propagating modes contribute negligibly to thermal condu...
متن کاملNeutron scattering study of the vibrations in vitreous silica and germania.
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 scattering. The method is applied to new room temperature measurements of vitreous silica and germania on the thermal time-of-flight spectrometer IN4 at the High Flux Reactor in Grenoble. The inelastic dynamic struct...
متن کاملQuantification of the bond-angle dispersion by Raman spectroscopy and the strain energy of amorphous silicon
A thorough critical analysis of the theoretical relationships between the bond-angle dispersion in a-Si, , and the width of the transverse optical Raman peak, , is presented. It is shown that the discrepancies between them are drastically reduced when unified definitions for and are used. This reduced dispersion in the predicted values of together with the broad agreement with the scarce direct...
متن کاملThe Phagocytosis and Toxicity of Amorphous Silica
BACKGROUND Inhalation of crystalline silica is known to cause an inflammatory reaction and chronic exposure leads to lung fibrosis and can progress into the disease, silicosis. Cultured macrophages bind crystalline silica particles, phagocytose them, and rapidly undergo apoptotic and necrotic death. The mechanism by which particles are bound and internalized and the reason particles are toxic i...
