معرفی
Ludovic Largeau is a CNRS Researcher and Head of the Materials Analysis Platform (PANAM) at the University Paris-Saclay's C2N. He specializes in structural and chemical analysis of materials at atomic and nanoscale levels using advanced techniques like X-ray diffraction (XRD), transmission electron microscopy (TEM), and cathodoluminescence. His expertise spans semiconductor heterostructures, nanowires, and oxide materials, with a focus on strain analysis and interface engineering. He leads a team of three engineers and has contributed to major projects like ANR EQUIPEX TEMPOS and the IPCEI miTPGaN initiative. His research has produced over 200 publications (h-index 37), emphasizing ferroelectric materials, epitaxial growth mechanisms, and photonic applications of doped oxides. Largeau has directed four theses and two internships, fostering collaborations across France and internationally with academic and industrial partners.
His research interests include the structural characterization of III-V semiconductors, graphene-based systems, and Ruddlesden-Popper oxide heterostructures. Key contributions involve developing XRD techniques (GIXRD, GPA) and aberration-corrected STEM methods for chemical analysis. He also explores strain mapping via 4DSTEM and investigates the growth dynamics of nanowires on unconventional substrates, such as graphene. Recent work focuses on optimizing III-V/Si integration for photovoltaics and nonlinear optics, alongside advancing functional oxide waveguides for integrated photonics.
