The Network Dynamics of Ge-Se Glasses and the Intermediate Phase
The objective of this proposal is to characterise the network dynamics for a range of GexSe1-x glasses (0 < x < 1) by using inelastic neutron spectroscopy to measure the... -
Transformations in B2O3 glass under pressure
B2O3 is a prototypical glass forming oxide material and is an essential component in many industrial glasses. Unlike SiO2 and GeO2 its structure under ambient conditions is not... -
Q-dependence of the single particle motion in a molten alkali halide
An inelastic X-ray investigation on the collective inelastic dynamics of molten NaCl revealed the remarkable result that the acoustic-like dynamics is similar to the dispersion... -
Density-driven structural transformations in calcium silicate glass
The density-driven structural transformations in the calcium silicate glass CaSiO3 will be investigated at pressures increasing to 17.5 GPa. This glass is one of a family of... -
The partial vibrational density of states for As2Se3 glass
The method of Se isotope substitution with inelastic neutron scattering will be used to measure the partial VDOS for As2Se3 glass. This is a prototypical network forming... -
The partial dynamical structure factors and vibrational density of states in ...
We wish to measure the partial dynamical structure factors and the partial vibrational density of states (VDOS) for the archetypal network forming glass GeSe2 by using the... -
Structure of GeSe4 glass using neutron diffraction with isotope substitution
The structure of GeSe4 glass will be measured using the method of isotope substitution in neutron diffraction with both Ge and Se isotopes. This material is representative of a... -
Structure of Ge-Se Glasses: Extreme Compositions
We propose to measure the structure of glassy Ge2Se3 and GeSe9 which lie at either end of the glass forming region in the Ge-Se system. The motivation is provided by the need to... -
Mechanism of network collapse in strong network glass forming systems
The object of this proposal is to investigate the mechanism of network collapse in the ¿strong¿ network glass forming system GeO2 in the pressure range between 9 and 16 GPa... -
Search for the Structural Origin of the Intermediate Phase
The object of this experiment is to search for the structural origin of the intermediate phase by making careful measurements of the structure of glassy Ge-Se which is a...
