OFFER DESCRIPTION

 

The postdoctoral researcher will conduct plasma magnetron sputtering deposition of complex alloy thin films using a combinatorial approach and their structural and chemical characterization. He/she will be involved in targeted properties analysis.

In the current context of the SARS-COV-2 pandemic, there is an urgent need to find “multi-material” solutions to prevent the formation of biofilms and to promote the bactericidal and virucidal properties of surfaces (metallic or plastic) in regular contact with users. Current solutions make it possible to limit the adhesion of bacteria (formation of biofilms) and are mainly in the form of adhesive films, with proven anti-bacterial properties. Their anti-viral properties, when they exist, do not cover the novel corona virus (SARS-CoV-2). They require long and frequent cleaning and disinfection steps.

The idea would therefore be to develop a multifunctional coating whose surface condition prevents the formation of biofilms as much as possible, composed of elements providing bactericidal and virucidal functions and which would have good abrasion resistance (cleaning cycles), to ensure long lifetime. We propose to study the ability of poorly ordered metallic multimaterials (among them "high entropy" or HEA alloys) to meet all these needs.

The work will aim at synthesizing thin films of complex alloys by plasma magnetron sputtering using a combinatorial approach in order to investigate a large range of compositions in a single experimental run. Control of the deposition conditions will be possible using gas phase diagnostics available at the GREMI (heat flux sensor, mass spectrometry, quartz micro-balance etc.). Deposited films will be analyzed by routine material analysis techniques: scanning electron microscopy, X-ray diffraction, atomic force microscopy, ion beam analyses… Functional properties (abrasion resistance, anti-viral and anti-bacterial activities) will by studied in the frame of a collaboration with the industrial end-user. In line with the experiments, the candidate will have the opportunity to carry out relevant molecular simulations of such thin film growth.
