Missions

ALD is a vapor phase deposition technique enabling the synthesis of ultrathin films of inorganic materials with a sub-nanometer thickness control. This technology presents unique benefits when compared to other liquid phase or gas phase deposition routes. First, ALD typically allows for the deposition of very pure nanomaterials. Another key-benefit of ALD is its high conformality, particularly when compared to other gas phase routes such as PVD. In fact, ALD can be used to coat complex 3D structures with a conformal and uniform layer of high quality materials, a capability unique amongst thin film deposition techniques. No other thin film method can even approach the conformality achieved by ALD on high aspect ratio structures. Consequently, ALD-grown materials have a wide range of applications, from biosensing to microelectronics, and from nanocatalysts to batteries.
The surface properties of the particles are one of the determining factors for the behavior of particulate systems especially in the batteries. The aim of this postdoc is the development and characterization of novel thin deposition films (based on oxide, fluoride and hydroxide) and mixed phases on powder. Our goal is to develop new original processes for the development of this thin film in order to improve the electrochemical properties of the powder in Batteries field. The postdoc will be divided into 2 main parts:
1) Coating of powders by thin film using the ALD
2) Characterisation of chemical, physical and electrochemical properties of the obtained materials

Activities

In connection with the project objectives, the candidate will
- carry out a review and bibliographical synthesis on the powder coating using Atomic Layer Deposition
- contribute to define the experimental protocols and their implementation.
- be responsible for development and characterization of the deposited thin films.
- participate to the electrochemical measurement
- prepare communication materials, reports and presentation.

Skills

The candidate must have a PhD in materials science, chemistry, nanomaterials or related fields. We are looking for a highly-motivated candidate with a strong interest in chemistry and materials science, having an experience in research laboratory or R&D and interested in transversal academic research with industrial goals. Interpersonal skills, dynamism, rigor and teamwork abilities will be appreciated. Candidates should be fluent in English. In addition, well-written English skills is highly recommended.
Additional information may be obtained by contacting Dr. Mikhael BECHELANY (mikhael.bechelany@umontpellier.fr) and Dr. Damien Voiry (damien.voiry@umontpellier.fr). Candidates can send a CV and a motivation letter by email to Mikhael.Bechelany@umontpellier.fr

Work Context

The postdoc will be held between an industrial partner and the European Institute of Membrane (IEMM).
The European Membrane Institute (IEMM) (Dr. M. Bechelany and Dr. D. Voiry) is a mixed research unit affiliated to ENSCM (National School for Chemical Engineers), University of Montpellier and CNRS. Main topics of IEMM are membrane chemistry, chemical engineering and membrane processes. The unit is composed of 55 permanent research staffs and 100 postdocs, PhD and master students, helped with 24 chemical engineers, technicians and administrative staffs.
