DATE LIMITE DE CANDIDATURE
The postdoctoral assignment will consist in operating the high-temperature ultra-high vacuum chamber that has been recently connected to the Nanoplast equipement (see nanoplast.pprime.fr). This unique experimental device makes it possible to mechanically stress samples by uniaxial compression over a temperature ranging from room temperature to 1500K. The features generated at the free surface (in particular the slip traces) are then characterized by scanning tunneling microscopy or atomic force microscopy.
The research activities are aimed to have a better understanding of the elementary plastic mechanisms taking place in complex materials and will be first focused on:
- Quasi-single-crystals (for instance AlCuFe) in collaboration with the Institut Jean Lamour of Nancy, France
- High entropy alloys (HEA), in collaboration with the Institute of Materials (ZGH) of the University of Bochum, Germany
- Cu(111) substrates coated with a few Au(111) monolayers known to exhibit surface reconstructions.
