Dislocation-based competition of plasticity and cracking in oxides: Understanding and application

Conference Dates

October 2 – 7, 2022


Dislocations in ceramic oxides are drawing increasing attention thanks to their promising properties, such as dislocation-tuned electrical conductivity, thermal conductivity, and electro-mechanical properties. However, due to the brittleness of most oxides at room temperature, it remains a great challenge to engineer dislocations without forming cracks, which is a prerequisite for harnessing the functionalities. From the aspect of mechanical deformation, nano-/micromechanical testing has been found to be a feasible approach to achieve this goal.
