Description
ALD is a vapor phase deposition technique that produces ultrathin inorganic films with precise sub- nanometer thickness control. This technology offers distinct advantages over liquid or gas phase deposition methods. Firstly, ALD enables the creation of exceptionally pure nanomaterials. Additionally, it excels in providing high conformality, especially when compared to gas phase methods like PVD. ALD can effectively coat intricate 3D structures with a uniform layer of top-quality materials, a capability unparalleled among thin film deposition techniques. Its exceptional conformality makes ALD-grown materials suitable for a wide range of applications, spanning biosensors, microelectronics, nanocatalysts, and 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 mission is to enhance cathode materials. Our objective is to gain a comprehensive understanding of the coating chemistry applied to these cathode materials and to assess the feasibility of Atomic Layer Deposition (ALD) as a coating method for these materials. Ultimately, the aim is to improve the performance of these materials when integrated into batteries. The mission will be divided into 2 main parts:
1) Coating of powders by thin film using the ALD
- Characterisation of chemical, physical and electrochemical properties of the obtained materials
Missions:
- Conduct ALD depositions following established protocols and Optimize deposition parameters.
- Accurately record experimental data, making detailed observations, and maintaining organized records.
- Collaborate with the research team to improve ALD processes for enhanced material quality and
- Assist in the post-deposition characterization of materials, including structural and chemical analysis, to support research
- Assist in the analysis of characterization data and contribute insights to the research
- Take ownership of laboratory equipment, ensuring proper functioning, calibration, and readiness for experiments.
- Diagnose and address equipment issues promptly to minimize Coordinate with external vendors for complex repairs if necessary.
- Maintain an organized inventory of laboratory supplies and detached pieces, ensuring adequate stock
- Exhibit strong troubleshooting skills when dealing with equipment
- Collaborate effectively with researchers and scientists to achieve research
Candidate profile
If you hold a Ph.D. in (nano)materials or chemistry or a related field and have a natural inclination for hands-on experimentation, you bring valuable practical abilities and problem-solving skills to our team. Your passion for learning and collaborative mindset make you an ideal candidate for exploring advanced techniques, such as ALD. We are looking for individuals with experience in a research laboratory or R&D setting who are interested in engaging in interdisciplinary academic research with
industrial objectives. Interpersonal skills, dynamism, attention to detail, and strong teamwork abilities will be highly valued. Proficiency in English is essential, and well-developed written English skills are strongly recommended.

The postdoc will work at the European Institute of Membrane (IEMM) in collaboration with a global industrial group “Umicore”. The European Membrane Institute (IEMM) 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.
