Hands-free defect engineering: Electric fields control motion of ceramic dislocations without need for mechanical loading

By Lisa McDonald / July 25, 2023

While some studies have demonstrated that electric fields and light exposure can affect the motion of dislocations in ceramics, the principal driving force of motion in these cases was mechanical stress. Now, an international group of researchers showed dislocation motion in a single-crystalline zinc sulfide can be controlled using only an external electric field.
