Anomalous Glide Plane in Platinum Nano- and Microcrystals

Abstract

At the nanoscale, the properties of materials depend critically on the presence of crystal defects. However, imaging and characterizing 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 submicrometer 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 noninvasive technique, both plasticity and unusual defect behavior can be probed at the nanoscale.

“…The reconstruction shown in Figure a is the same as that in Figure d but viewed from a different angle. Such one-dimensional crystal defects are confirmed as dislocations from the phase (atomic displacement) discontinuity in their local displacement fields …”
