Jean-Christophe Harmand

Jean-Christophe Harmand is a CNRS Senior Researcher (DR1) and heads the Department of Materials at the Center for Nanoscience and Nanotechnology (C2N), a joint unit of CNRS and Université Paris-Saclay. He has held key roles including Deputy Director of C2N since 2016. His career spans over 35 years in semiconductor materials research.

Education:

• PhD in Physics, University Paris 7 (1988)
• Habilitation à Diriger des Recherches, University Paris 7 (1998)

Research Focus: Specializes in real-time monitoring of nanostructure growth via molecular beam epitaxy (MBE), nanowire growth mechanisms, and nanowire applications in photovoltaics/photonics. Pioneered MBE integration with transmission electron microscopy for atomic-scale growth observation.

Awards:

• CNRS Silver Medal (2012)

Leadership Roles:

• Coordinated 30+ teams in the French GdR Nanofils et Nanotubes Semiconducteurs (2006–2014)
• Developed GaNAsSb epilayers and metamorphic transistor structures

Labs & Infrastructure: Principal investigator at C2N, leveraging unique MBE-TEM facilities for in situ nanowire growth analysis.
