LSPM (Paris)

The LSPM  is a CNRS unit with around 140 persons. The scientific objective is to develop basic and applied research in materials science and processes. 3 axes are defined:

  1. Development of materials elaboration and transformation processes ;
  2. Study of the relationships between materials microstructures and functional properties ;
  3. Materials for devices and processes.

Strong interactions between chemists and physicists belonging to 7 teams lead to the following researches:

  1. Thin films growth and surface treatments by PVD techniques: diamond, oxydes and metallic glasses.
  2. Elaboration of new phases under high pressure and high temperature conditions.
  3. Elaboration of functionalized nanomaterials by soft chemistry.
  4. Elaboration and transformation of materials by thermomechanical treatments.
  5. Plasticity and recrystallization of crystalline metallic materials under thermomechanical solicitations.
  6. Behavior, damage and fracture of brittle materials or with limited ductility.
  7. Interaction plasma-materials for edge tokamak plasmas.
  8. Materials for devices and energy: hydrogen (transport and stockage), photonic and photovoltaic.
  9. Electromagnetic and mechanical properties of thin films and nanostrutures

LSPM belongs to the association Sorbonne Paris Cité (SPC) which contains 4 universities (Paris 13, Sorbonne Nouvelle, Paris Descartes et Paris Diderot) and 4 « grandes écoles or institutes » (Sciences Po, l’Ecole des Hautes Etudes en Santé Publique, l’Institut National des Langues et Civilisations Orientales et l’Institut de Physique du Globe de Paris).

LSPM belongs to “laboratoire d’Excellence” Labex SEAM (Science and Engineering of Advanced Materials and Systems) created in 2011. This is a joined project with the LPL (UP13) and 3 other laboratories from Paris-Diderot university (MPQ, ITODYS and MSC). It enables collaborative and interdisciplinary work in many fileds (photonics, spintronics, plasmonics).

Role in the project

LSPM will perform ab-initio calculations of structural and elastic properties of single-crystal ordered  and disordered TiAlXN nitride solid solutions using virtual crystal (VCA) and coherent potential (CPA)  approximations, and calculations of the effective elastic properties of the polycrystalline materials using a self-consistent averaging method. Advanced experiments, such as Brillouin light scattering (BLS), will provide some reference values on elastic properties for comparison with computational predictions. This experimental validation is envisaged further as a feedback that should lead to modifications and improvements of the calculations.

Involved staff

  • Philippe Djemia (Prof.) is an expert in the field of surface acoustic waves and elastic properties of hard coatings and multilayers and started 7 years ago ab initio calculations in semiconductors but more recently on ternary TMN. His current research interest lies in the determination of the relationship between elastic & plastic properties of coating. He is WP-leader of WP2.
  •  David Tingaud (Assoc. Prof.) . His activities concern the elaboration and sintering of nanostructured and ultrafine grained materials, the microstructure and mechanical properties and the atomic scale simulations (sab initio, molecular dynamics).
  • Damien FAURIE (Assoc. Prof). His implication in the project is related to his expertise in multi-scale modelling of the elastic properties of polycrystalline materials by numerical averaging methods similar to the Eshelby inclusions problem.
  • One Post Doc should contribute and work on DFT calculations of elastic constants of binay, ternary and quaternary alloys principally using SQS methodology as proposed by IFM (Ferenc Tasnadi).
