Plasmas and Thin Films (PCM)

The Plasmas and Thin Films team conducts research into the development of cold plasma processes for the deposition and etching of thin-film materials. Our research also includes physico-chemical processes other than plasmas alone, such as plasma solution injection and chemical dealloying. At the heart of the team’s activities are the detailed study of plasma/surface interaction mechanisms, the development of new plasma processes, the implementation of multi-scale numerical modeling in support of experimental activity, and the characterization of a material with a view to a given property. The team’s research strategy is therefore based on an iterative approach to these four pillars, enabling optimization of the synthesis or processing of a material with targeted properties.

The research projects developed by the PCM team have applications in several technological sectors:

  • microelectronics,
  • micro- and nano-technology,
  • optoelectronics,
  • photocatalysis,
  • sensors,
  • energy conversion and storage,
  • coatings and surface treatments.

Activities are structured around four research themes: etching, thin-film deposition, nano-object and nanocomposite synthesis, supported by a cross-cutting modeling theme.

The team collaborates with external partners who have the technological means for microfabrication to integrate materials into a device.
