Après dopage, les oxydes de terres rares peuvent acquérir des propriétés optiques intéressantes pour les dispositifs d’optoélectronique du futur. Ces matériaux peuvent aussi être utilisés comme absorbant neutronique dans les réacteurs nucléaires. Que ce soit pendant le processus de dopage ou en réacteur, ces oxydes sont soumis à des conditions d’irradiation aux ions intenses. Il est alors important de comprendre leur comportement dans cet environnement extrême. C’est l’objectif de cette thèse durant laquelle a été menée une étude fondamentale de matériaux modèles (couches épitaxiées assimilables à des monocristaux) sous irradiation ionique. Les principaux résultats montrent qu’un changement de phase, de cubique à monoclinique, se produit so...
