Recherche et Innovation en Electrochimie pour l'Energie
- Electrochemical atomic force microscopy (ECAFM) mode, with a spatial resolution less than 100 nm, will uniquely provide simultaneous capture of topographic, electrochemical, electrical, and mechanical maps with nanometerscale lateral resolution. It will allow the visualization, at the nanoscale, of electrical and chemical processes in liquid.
- Quantitative Nanoscale Mechanical (QNM) characterization will allow to map and distinguish nanomechanical properties, including modulus, adhesion, dissipation and deformation with up to atomic resolution.
- Kelvin probe force microscopy (KPFM) mode will provide a high spatial resolution and accurate measurements of surface potential, allowing for a highresolution workfunction mapping.
