Having just arrived at the Laboratory of Condensed Matter for Physics (PMC**), Clémence Badie is an expert in Atomic Layer Deposition (ALD), a technique that involves growing a thin layer of material at the nanometric scale on a given support (the substrate) in a vacuum reactor in a controlled manner. Since her Master's 1 internship at the University of Erlangen in Germany, the young researcher has continued to hone her skills in this field. “I cut my teeth working with a postdoctoral researcher who, even back then, showed me how to perform the manipulations that I will be carrying out here at the PMC.”

Clémence Badie's research focuses on the development of nanometric thin films using atomic layer deposition (ALD) for applications related to energy transition. She first specialized in ALD during her PhD, where she developed a hydrogen-selective membrane (2018-2022). Clémence Badie then further developed her ALD skills during her postdoctoral research, which focused on the deposition and characterization of electroactive thin films (2022-2025). She is currently studying the relationship between thin films—such as single- or multi-element nitrides—and their electrochemical properties. At the same time, Clémence Badie teaches in the chemistry department at École Polytechnique.
