Sebastien Saitzek
was born in August 9th, 1976 in Arras (Région Hauts-de-France / 62). In march 2005, he obtained his PhD degree in Materials Science at the Toulon University under the supervision of Prof. J. R. Gavarri and Prof. Ch. Leroux. His thesis was on the catalytic study of CeO2/CuOx nanocomposite and the development of CeO2/VO2 thermochromic bilayers for optical applications in the infrared range. In september 2006, he was recruited as Associate Professor at Artois University and joined the “Laboratoire de Physco-Chimie des Interfaces et Applications (LPCIA)”. In 2008, he integrates the thin film and nanomaterials team (CMNM) of Catalysis and Solid Chemistry Unit (UCCS UMR CNRS 8181). In december 2011, he received his HDR (Habilitation) at the Artois University under the supervision of Prof. R. Desfeux. Then, he was promoted full professor in september 2018. His research focuses on the elaboration of oxides (layered perovskite families) in nanomaterials and thin films forms by soft-chemistry and pulsed laser deposition. His research activities cover the field of optics, electronics and energy.




Keywords: Sol-Gel, Pulsed Laser Deposition, X-ray diffraction, ferroelectricity, piezoelectricity, luminescence, photoconductivity
