Ludovic Largeau

Ingénieur de recherche CNRS

Ludovic Largeau est le responsable de la plateforme d'analyse des matériaux (PANAM). Il encadre 3 ingénieurs.

Ensemble, ils développent leurs connaissances et leurs outils d'analyses structurales et chimiques des matériaux à l'échelle atomique aussi bien qu'à l'échelle nanométrique dans le cas des caractérisations optiques.

La plateforme dispose de la dernière génération d'équipements pour la diffraction des rayons X (DRX), la microscopie électronique (MET) par transmission avec microanalyse (EDS), la microscopie à force atomique (AFM) et la cathodoluminescence résolue en temps (CLRT).

 

Il a personnellement dévelopé des techniques en diffraction des rayons X comme GIXRD, HRXRD, figure de poles, réflectivité, et in-operando. Il est aussi spécialisé dans la correction des aberrations sphériques en mode STEM et des techniques associées pour l'analyse chimique (high angle annular dark field HAADF, energy dispersive X-ray spectroscopy EDXS and energy filtered TEM EFTEM). Il a aussi développé les analyses du champ de contraintes par analyse géométrique de phase en utilisant les images STEM haute résolution, la diffraction de faisceau éléctronique convergent (CBED) et les cartographies de phase et de contrainte par 4DSTEM.

 

Son domaine de recherche porte sur les interfaces d'hétéosystème et de III-V nanofils, sur les IV-IV semiconducteurs,sur le graphene et sur les oxydes cristallins.


Il a été à l'origine du projet d'ANR Equipex Tempos (2010-2022). Il a été responsable du sous projet Nanomax, la plateforme d'analyse nanométrique structurale et chimique. Et il a participé au cahier des charges de la plateforme de croissance in-situ (Nanomax).
Il est le pricncipal investisseur dans le projet IPCEI miTPGaN ein collaboration avec XFAB.

Il a de nombreuses collaborations, aussi bien en France qu'à l'international avec des institutions privés et publics.
Il a dirigé 2 stages et 4 théses.
Il est auteur et co-auteur de 202 publications, son h-index est 37.
