Résumé
Unravelling the connection between the macroscopic properties of glasses and their amorphous structure is probably one of the hardest as well as the most rewarding task to pursue, in condensed matter. The employment of chalcogenide glasses can foster these studies since they allow one to easily tune the microscopic structure via a change either of composition or temperature. We propose to perform an x-ray photon correlation study of these glasses to evaluate the beam-induced relaxations. We aim at unveiling the influence of the amorphous structure on the dynamic modifications induced by x-rays.
