Les matériaux à changement de phase (PCM, Phase Change Materials) sont utilisés dans les dispositifs mémoires PCRAM (Phase-Change Random Access Memory), dans lesquels l’information est stockée par l’état du PCM (cristallin ou amorphe, correspondant aux deux états d’information 0/1). La lecture se fait par la mesure de la résistance du PCM qui est très différente suivant son état amorphe ou cristallin. L’optimisation et la fiabilité de ces dispositifs mémoires repose sur une compréhension fine des mécanismes physiques à l’œuvre lors de la transition amorphe-cristal. Pendant cette thèse, un système modèle (GeTe) a été caractérisé in situ au synchrotron. Le comportement thermoélastique et le mécanisme de cristallisation ont été étudiés pour pl...
