Abstract Scope |
The design of new materials rely on the knowledge of the structure/property relationship, which often originates from the material sub-micrometric scale structure. Crystalline materials are of major importance in this field, with applications from microelectronics and energy, to biomimetism. Material science calls for imaging approaches able at describing complex crystalline materials at the nanoscale, in 3D, further combining in situ/operando compatibility and high spatial resolution. In this context, the advents of x-ray Bragg ptychography have opened promising perspectives filling the gap between direct microscopies (AFM, SEM, TEM) and x-ray Bragg diffraction analysis.
Here, the interest of Bragg ptychography will be illustrated by a series of applications, including detailed characterization of stacking faults in a quantum nanowire, impact of ionic implantation in a polycrystalline metallic material, comparison of different crystallisation mechanisms in calcareous bio-inspired films and 3D imaging of crystalline properties in mollusk shell biominerals. |
