Offer Description

The recruited candidate will participate to the installation and testing of an ion source for helium implantation in functional material for property tuning. The crystalline structure and functional properties post-implantation characterizations is among the contract's objectives.

This post-doc is included in a research project aiming to study the effect of helium implantation on the functional properties in different materials (ferroic properties, metal-insulator phase transitions). The project is structured in 3 axes. A first axis on the sample fabrication and helium implantation in which the aim is to install and test a new equipment (helium source) to implant thin films synthesized in the laboratory by pulsed-laser deposition (PLD). A second axis to study the effect of implantation on the crystalline structure of the samples, which will rely on structural characterizations (XRD, electron and scanning probe microscopy such as AFM). And a third axis to study the effect on the functionality of the studied materials (transport measurements, piezo-force microscopy (PFM), magnetic measurements…).

The work will take place at the CRISMAT laboratory and will focus on the installation of the helium source in a vacuum chamber already present in the laboratory, the tests for implantation and the structural and functional characterizations post-implantation. Scientific communication (working on publications, going to conferences) will be part of the work. The PLD synthesis of the studied samples can also be part of work depending on the profile of the candidate. The expertise of the laboratory's research teams will support the work of the candidate.

• fluent written and spoken English
• ability to organize and follow-through an experiment plan
• scientific autonomy
• An experience in ion implantation, PLD thin film synthesis and/or functional material characterization or crystallography, as well as an experience in experimental development will be a plus.
