Philippe Moreau
Université de Nantes - CNRS, UMR6502, 2, rue de la Houssinière, 44322 NANTES cedex, FRANCE
Philippe Moreau is a graduate of the
Ecole Nationale Supérieure des Industries Chimiques (ENSIC
in Nancy, France : "Grande Ecole" specialised in Chemical
Engeneering). During his PhD, his focus became redirected towards
the study of materials. The subject was "Interactions in mercury
intercalated TiS2 and TaS2" under the supervision of Prof. G.
Ouvrard at the Institut des Materiaux Jean Rouxel in 1994. While at
the Cavendish Laboratory (Cambridge, England) in his postdoctoral
position under the supervision of Prof. A. Howie, he got involved
in Electron Energy Loss Spectroscopy and still is involved in this
field to date. He became Maître de Conférences (lecturer)
at the University of Nantes in 1998 and teaches inorganic chemistry,
electron microscopy and, photon and electron based spectroscopies.
His current interests are in the study of lithium battery materials
using EELS and electron microscopy, the development of the understanding
of the low energy loss region in EELS spectra and the optimised comparison
of experimental spectra with ab initio calculations.
Research Interests Statement
The powerful balance between chemistry
and physics becomes increasingly obvious with each passing day, especially
as far as the study of materials is concerned. Their macroscopic physical
properties are often linked to their more local chemistry, i. e. the
"chemical bond", which was very dear to late Prof. Jean Rouxel
(founder of the Institut bearing his name). This "chemical bond"
results directly from the electronic structure of the material. The
determination of which, is thus a major challenge in order to get a
better understanding of the material properties. In the context of the
ever-growing miniaturisation of devices and the tremendous development
of nanomaterials, a localised probe of this electronic structure
becomes essential and Electron Energy Loss Spectroscopy in a Transmission
Electron Microscope is the ideal tool (see our Microscopy
Centre site). With an energy resolution of less than an eV and a
probe smaller than 1 nm, EELS has revealed unrivalled possibilities
See
D. Muller papers . If one wants to go beyond the "finger print"
analysis of the EELS spectra obtained, ab initio calculations
of the spectra are necessary. These calculations, within the Density
Functional Theory (DFT), are also essential tools in the visualisation
of the electron density in the materials. Consequently, performing the
experimental EELS technique and the theoretical DFT calculations
in parallel, constitutes one of the most promising research paths in
view of understanding structures and properties of new materials.
