Arnaud Le Febvrier

Docent in materials science

My research is focused on fundamental and application-inspired studies of coatings, whereby the defects in the materials are introduced/controlled for enhanced physical properties. Various applications are aimed: thermoelectric, hard coating, protective coatings, fuel cell, and optical active applications are few of them.

Research interest

My research interest involves the design, development, and understanding of physical properties of coating for promising thermoelectric/electrical/mechanical properties by controlling defects in a material. Inserting defects (0D, 1D, 2D, 3D) in a control manner can enhance targeted physical properties. This implies a high level of control of the material synthesis and of understanding the induced properties. I have a particular interest in the control of defects in nanocomposite and their potential in improving and/or opening new doors for several application domains.

Teaching

My main teaching activities include a vacuum sciences and technology course at a PhD level and few interventions in the bachelor level program for applied physics with labs/supervision of project.
