Anomalous Glide Plane in Platinum Nano- and Microcrystals
Résumé
At the nanoscale, the properties of materials depend critically on the presence of crystal defects. However, imaging and characterising the structure of defects in three dimensions inside a crystal remain a challenge. Here, by using Bragg coherent diffraction imaging, we observe an unexpected anomalous {110} glide plane in two Pt sub-micrometer crystals grown by very different processes and having very different morphologies. The structure of the defects (type, associated glide plane and lattice displacement) is imaged in these faceted Pt crystals. Using this non-invasive technique both plasticity and unusual defect behaviour can be probed at the nanoscale.
