The Research Line In Situ/Operando Characterization has two topics. The first one aims at mastering the growth and crystallization of ultra-thin films and nanostructures (oxides, sulfides), by the knowledge of the mechanisms at atomic and nanometric scale. To address that issue, we develop and use dedicated tools and experimental methods in order to determine chemical, spectroscopic, structural and optical information at the very onset of nucleation and as growth proceeds (ellipsometry, residual gas analysis, synchrotron radiation). The targeted processes are atomic layer deposition (ALD), as well as metal-organic chemical vapor deposition (MOCVD) and chemical bath deposition (CBD). The second topic involves advanced chemical and structural chatacterizations of nanostructures and nanomaterials that are used in an ex situ manner (after fabrication) or in an in situ manner when the effects of an external sollicaition are investigated (temperature, annealing under controlled atsmosphere, electromagnetic fields, electrochemical forces...), or in operando. The experimental characterization techniques used are mainly transmission electron microscopy, Raman spectroscopy, X-ray diffusion, X-ray absorption spectroscopy, anomalous X-ray diffraction, and photoelectron spectroscopy.
