CNRS Senior Researcher (DR1)
After studying at Ecole polytechnique (X75), I received my state PhD degree (doctorat d’Etat) in physics from Université Paris-Sud in 1986. I am currently senior scientist (DR1) at CNRS, in charge of the group 'Elaboration and physics of epitaxial structures' at C2N (Palaiseau) and of the CNRS/RFBR International Research Project 'Physics of nanostructures and innovative devices based on compound semiconductors'. My research deals with III-V semiconductor alloys, heterostructures and nanostructures. I have studied experimentally and theoretically the thermodynamics of these systems and their instabilities, their growth modes and growth kinetics as well as strain relaxation and local order. In 1985, I demonstrated for the first time, by transmission electron microscopy, the formation of self-organized quantum dots. I have spent most of the last 15 years studying semiconductor nanowires, focusing on the analysis, the understanding and the modeling of the fundamental mechanisms which govern their formation, on the specificities of their structure and on the fabrication of nanowires with controlled local structure and composition. I have authored more than 140 publications totaling 6000 citations, with a h-index of 38. In 2015, I was elected Honorary member of the prestigious Ioffe Institute (Saint Petersburg), a distinction granted to only one foreign scientist each year.
