The focus Energy materials is supervised by Philippe Pareige and involves the skills of 5 of the 7 member laboratories. In 2011-2017, 24 research projects have been funded by the LabEx EMC3 on that research axis: 14 short-term projects, 8 long-term projects and 2 Attractiveness projects for a total amount of 5,153 k €. Please find hereunder the different divisions of this focus.
Thermo electric materials
This work package, led by Sylvie Hébert, aims at creating performing and competitive new thermo electric materials. To obtain these results, three options will be explored. A synthesis work on silicides and oxydes in order to improve their thermo electric properties, the creation of hetero-structure as model systems allowing the variation of several parameters and a section more explorative on hybrid materials.
Project example: Controlling the dissemination of phonons in composite materials to upgrade the figure of merit of thermo electric materials or decrease the thermic and electronic conduction of structural materials. Thus, studying the dissemination of nano charges into polymer matrices is a major issue in the research and industrial sectors.
Involved laboratories: CRISMAT – LOMC – LCMT
Materials for light emission
This work package, led by Xavier Portier, aims at getting thin layers to develop optical devices compatible with CMOS, lasers and LED. Several paths are explored: thin film nanostructure doped with rare earth element, fluoride doped with praseodymium as well as III-IV semi-conductors. In a longer term, a work package on organic study could be developed.
Project example: Studying new nanostructured silicium-based structures and doped with rare earth ions for the future generation of white LED. The final goal of this fundamental research project is the development of a prototype device.
Involved laboratories: CIMAP – CRISMAT – GPM
Materials for nuclear energy
This work package, led by Bertrand Radiguet, aims at understanding the aging mechanisms of materials under irradiation used in the nuclear sector: structural materials of current and future reactors, nuclear fuel cladding, ceramic and organic materials in the waste management. It will help understand the mechanisms and microstructural bases of the evolutions in use properties.
Project example: Acquiring an irradiation tool to simulate the aging under irradiation of the materials is essential. The aim is to purchase an ion implanter-accelerator dedicated to this topic and available to other axes of LabEx EMC3 especially for the modification of materials properties by implantation.
