AbstractAbstract
[en] We propose in this work a structural study of B2S3-Li2S glass system through the use of neutron scattering, X-ray photo-electron spectroscopy and computerized simulation. We have got information on the order at low and short distance range of these glasses. This information has been correlated to changes in physical features like ionic conductivity, density and temperature of the vitreous transition according to their chemical compositions. The knowledge of the local order in the most modified binary glasses has allowed us to propose a model for ionic conduction similar to the model used for ionic crystals. This model has been validated: it yields an activation energy that agrees well with experimental data
