For nearly a century, scientists have understood how crystalline materials—such as metals and semiconductors—bend without breaking. Their secret lies in tiny, line-like defects called dislocations, ...

Plastic deformation of crystalline materials with isotropic particle attractions proceeds by the creation and migration of dislocations under the influence of external forces. If dislocations are ...

The diagram shows the effect of 'sliding' an Edge (a), Screw (b), or Mixed (c) dislocation completely across a slip plane in the crystal. Each dislocation has the same effect as it moves completely ...

Researchers and industries have been using transmission electron microscopy (TEM) to study semiconductors' stacking and dislocation faults. This article considers the analysis of crystal structures.

Jogs and kinks are atomic scale changes in direction of a dislocation line. Jogs are out of the slip plane and kinks lie in the dislocations slip plane. For the edge dislocation shown, the jogs are of ...
