VIDEO - CoWork series - Atomic Resolution Imaging by Electron Ptychography, with David A. Muller

Electron microscopes use electrons with wavelengths of a few picometers, and are potentially capable of imaging individual atoms in solids at a resolution ultimately set by the intrinsic size of an atom. With recent advances in detector technology and reconstruction algorithms, the resolution of…

VIDEO - CoWork series - Magnetic chirality in multilayers probed by Soft x-ray (coherent) scattering, with Nicolas Jaouen

Many current forthcoming applications of magnetic materials involve heterostructures or alloys containing magnetic and non-magnetic elements. X-ray Resonant (Coherent) Scattering is the technique of choice to probe such phenomena thanks to its element-selectivity and spatial sensitivity.
