Post-Doctoral Position In Materials Science

Nanostructured materials often exhibit physical properties different from those of their bulk counterparts. In such materials, interfaces may govern mechanical properties. Thus, it appears necessary to gain insight into the interactions between interfaces and extended defects (such as dislocations and mechanical twins) with the aim to improve the nanostructure of plastically deformed materials.

The post-doctoral work will consist in examining, by means of atomic-scale simulations, bi-metallic Cu/Ag multilayers in which different types of semi- coherent interfaces can coexist. The recruited person will have to study the global response of the whole system and identify new elementary mechanisms involved in the formation and extension of mechanical twins during plastic deformation for systems with one or several interfaces. Special attention will be given to the role of the misfit interfacial dislocations mesh. For these systems containing several millions of atoms, classical molecular dynamics calculations will be performed (LAMMPS code) using the embedded-atom method interatomic potentials. Calculations will be mainly performed on local or regional computers; an application for access to national resources (GENCI) will also be made. Depending on the profile of the recruited person, it will be considered to assess the influence of strain rate using accelerated molecular dynamics techniques, and/or Nudged Elastic Band (NEB) calculations.

Application code to recall: 0GB04

Application form

The proposed contract is for a duration of 16 months with a scheduled starting date November 14, 2022. Some flexibility for the latter can be granted depending on the availability of the candidate.

The post-doc job must start no later than three years after completing the Ph.D.

Work at Pprime Institute takes place within the framework of a ZRR (restricted area) and the access is subject to authorization. Thus a 2-month delay is to be expected before acceptance.

Monthly gross remuneration: 2667€ or 2916€ depending on the profile of the candidate

Physics: PhD or equivalent

The candidate should have the following specific skills:

An experience in NEB or accelerated molecular dynamics methods would be a plus (but not mandatory).
