Beam-induced atomic motion in alkali borate glasses
Abstract
Applying coherent x rays using the method of atomic-scale x-ray photon correlation spectroscopy results inbeam-induced dynamics in a number of oxide glasses. Here these studies are extended to rubidium and cesiumborates with varying alkali contents. While no effect due to cumulative beam damage is observed, the observedrate of structural rearrangements shows a linear relation to the instantaneous dose rate. In agreement with theincreasing glass transition temperature, the rate of dynamics at a given dose rate decreases with increasingalkali content, while the shape of the decay of correlations becomes progressively stretched. This behavior isexplained in terms of faster dynamics of the alkali positions compared to the borate network. Finally, the q-dependentbehavior of the correlation decay rate implies that the observed dynamics proceeds via small-scaleatomic displacements subject to de Gennes narrowing.
