Supraconducteurs HTc et Traitement du Signal

Les objectifs de cet axe de recherche sont l’étude des propriétés de matériaux supraconducteurs à haute température critique (SHTC) et leur développement pour la réalisation de dispositifs, notamment dans le régime radiofréquence.

Concernant les études amont, nous avons d’une part montré comment la fonctionnalisation des films à l’échelle nanométrique permettait de manipuler de façon cohérente un réseau de vortex, et d’autre part proposé des concepts novateurs dans le domaine des applications sécuritaires et du traitement intelligent du signal.
