Centre National de la Recherche Scientifique (CNRS)

CNRS is composed of two teams, located at Laboratoire d’Etude des Microstructures
(LEM), a joint research unit belonging to CNRS and ONERA (UMR 104,
(http://lem.onera.fr/) and Centre Interdisciplinaire de Nanoscience de Marseille, (UMR 7325,
http://www.cinam.univ-mrs.fr/cinam/index.php), a joint research unit between CNRS and
Aix-Marseille University.

CINAM is an interdisciplinary laboratory focused on Nanoscience. Atomistic Computer
Simulation Group is one of its five departments, with currently 8 research fellows and 5 PhD
students or postdocs. Dr Christophe Bichara, former head of this group (2006-11),
(http://www.cinam.univ-mrs.fr/cinam/spip.php?page=perso&name=BICHARA), is Research
Director at CNRS with an expertise in Computational Materials Science. He graduated in
Chemical Engineering and obtained a PhD in Physics at Aix-Marseille University. His current
interest lies in the study of disorder, liquid matter, non-crystalline materials as well as the
growth mechanisms of carbon nanostructures. Until September 2013, he is coordinator of a
research project, funded by the French National Research Agency, devoted to the
“Selective and Optimized Synthesis of Carbon Nanotubes”, grouping five teams with a total
funding of 900k€ over 42 months. He published 80 papers, (h-index 18) on subjects ranging
from statistical mechanics, alloy thermodynamics, theory of liquid and amorphous matter
and carbon nanostructures synthesis.

LEM is one of the pioneering labs in France for its research on nanotubes and derivative
structures. Since 15 years, researches are conducted for synthesizing different kinds of
single wall nanotubes, determining their structural, electronic and optical properties and for
understanding and modelling the growth of nanotubes and graphene, Experimental aspects
include the synthesis of C, CNx and BN SWNT, transmission electron microscopy (TEM)
studies (structural analysis via high resolution TEM imaging and electron diffraction, as well
as compositional and dielectric properties measurements via electron energy-loss
spectroscopy (EELS) and in-situ heating experiments). The work carried out at the LEM on
the nucleation and growth of SWCNTs synthesized via high temperature methods, which
have been studied and modelled on the basis of detailed TEM and EELS analyses of the
relationships between catalytic particles and nanotubes, is now a reference. More recently,
LEM has identified by TEM two nucleation modes of C-SWNT in CVD techniques thanks to
an original technique for preparing electron-transparent membranes supporting the NT
growth and enabling analysis of the tubes in their native state.

Hakim Amara is research scientist at LEM (25 papers, 400 citations, H index: 10). Together
with Dr Bichara at CINaM, he developed an original approach to study carbon nanotube
growth, based on the use of an order N tight binding model coupled to a Grand Canonical
Monte Carlo method.
