Material properties for energy saving

PM2E team develops characterization techniques (high-resolution transmission microscopy, X-ray diffraction, thermo-mechanical testing) and multi-scale modeling (ab-initio, empirical potentials, finite elements) to obtain quantitative data on material properties. The aim is to attain a deepest understanding of the properties of materials that have applications in energy saving.

Research Topics

I. Semiconducting materials and devices

• Ia. Optimization of light-emitting devices : LEDs based InGaN (collaboration with national Laboratory of excellence GANEX, academics and industrial partners).
  

• Ib. Optimization of the materials quality and device (Al, In, Ga)N/GaN heterostructures for High Electron Mobility Transistors (HEMT) (European collaborative and industrial partners).
  

II. Plant fiber reinforced composite materials

• The main objective is the understanding of the relationships between the properties-microstructure and manufacturing. Above all, these materials are relatively sensitive to the environment. Moreover, the intrinsic nature and microstructure of plant fibers require multi-scale investigations.
