Physics of materials and nanostructures (PMN) group
The PMN group (Physics of Materials and Nanostructures) brings together solid state physicists and materials chemists around three thematics:
Nanoobjects Nanopores: This thematics is focuses on the design, caracterisation and manipulation of individual nanoobjects and nanopores, to understand and modify their own properties, or to use it as test systems in new caracterisation methods and manipulations at the nanoscale.
Interactions at bio-interfaces: Our studies are about developing biomaterials for tissue engineering, physicochemical transformations of nanoparticles used in food formulation, the development of functional hybrid materials, or the impact of the presence and internalization of nanoparticles on the (bio)physical and mechanical properties of living cells.
Quantum materials with non-conventional properties and functionalities: The production and study of complex materials with remarkable electronic properties, such as insulator-metal transitions (resistive transitions, Mott Insulators, and RRAM applications), induced by electric field for example.
Expertise and tools
All the 3 thematics use their expertise in different fields at the nanometer scale:
- Optical and vibrational spectroscopy,
- AFM microscopy,
- Atomic scale modelling of physical properties,
- Transport and magnetotransport,
- Physical chemistry in confined environments and at interfaces,
- Exploratory synthesis – nanostructures assembly.
And different investigation tools :
- Raman Diffusion and IR Absorption spectroscop,
- Electric transport measurement techniques,
- Near field microscopy and atomic force microscopy,
- Nanostructure characterisation (Zeta potential, DLS),
- DFT and MD modelling (AIMPRO, SIESTA, LAMMPS, DFTB+.
We often develop new and original tools specific to the problem being studied.
Group members are active in teaching in physics and chemistry of materials and nanostructures at:
- Nantes University Science and Technology Faculty (Physics and Chemistry Department), responsible for level 1 Masters courses in Analytical Chemistry, and Physics.
- The ‘Ecole Polytechnique’ Materials Department, Nantes University
- Nantes IUT (Materials Science and Engineering Department)
as well as outside Nantes. Notably we are strongly involved in the 2nd year Masters course in nanoscience and nanomaterials, ‘M2 C’NANO’ between Rennes and Nantes.
Contracts and Collaborations:
Multiple regional, national and European contracts:
- many academic collaborations (Spain, England, Japan, Australia, …)
- industrial collaborations at regional (Arclyn, Lemer PAX, ...), national (Hutchinson - Total, ST Microelectronics, RTE, Bolloré, Solvionic, ...) and international level (Solvay, Sensotran, ...).
