Parcours de recherche

Mon domaine d’expertise est la fabrication de dispositifs à l’échelle nanométrique tirant parti du degré de liberté du spin. J’ai été le pionnier de systèmes et de concepts originaux dans le domaine de la spintronique, évoluant vers des dispositifs multi-stimuli, à la frontière entre la physique, la science des matériaux et la chimie.

Lorsqu’on atteint l’échelle nanométrique, la predominance possible des propriétés quantiques et l’augmentation des forces de gradient magnétique conduisent à de nouvelles propriétés. Je suis intéressé par les applications interdisciplinaires de ces concepts, en électronique moléculaire ou organique, en nanofluidique et en (électro)chimie.

Recherche actuelle

Détecteurs électroniques 2D : en utilisant des matériaux 2D comme interface ou électrodes, et en tirant parti de leur dopage accordable, nous étudions comment il est possible d’interfacer ou de détecter un changement des propriétés opto-électroniques de molécules, de quantum dots ou de nanoparticules adsorbés.
Dispositifs multi-stimuli : les systèmes multiferroïques présentent l’avantage de pouvoir contrôler leurs propriétés de déformation, électriques et/ou magnétiques par des moyens optiques. Ces propriétés croisées ouvrent de nouvelles perspectives de multifonctionnalité ou d’amélioration et de contrôle des propriétés des dispositifs. Les matériaux hybrides solides/molécules sont également de bons candidats pour la construction de dispositifs de commutation déclenchés par de multiples types de stimuli.
Forces magnétiques : la réduction de la taille augmente les forces de gradient magnétique, ce qui rend possible le contrôle des propriétés de transfert de charge a l’interface solide-liquide (électrochimie) ou le contrôle du transport de fluides (nano et microfluidique). L’objectif est de tirer parti des concepts matures de la spintronique et du magnétisme pour fournir de nouveaux moyens d’influencer ces propriétés à l’interface.
