Deform to perform: dislocation-tuned properties of ceramics.

Kurzbeschreibung (Abstract)
Most materials science textbooks teach us that ceramics are infamously brittle due to the strong ionic and/or covalent bonding, and thus display little or almost no plasticity, particularly at room temperature. Yet there are growing reports of ceramic materials (predominantly in single-crystal form) that can plastically deform at room temperature, with some of these discoveries tagged as “surprising” (for strontium titanate) or “extraordinary” (for zinc sulfide). How are researchers achieving such counter-intuitive results? While several techniques have brought limited success (described in the next section), methods for engineering dislocations into ceramics have led to the most significant developments. This article will summarize these developments and consider what is next for the field of dislocations in ceramics.
