Plastic deformation in metals and alloys is governed by the generation and evolution of defects of point, line, plane and volume types 1,2. Among these defects, stacking fault tetrahedra (SFT), ...

Atomic-scale understanding and control of dislocation cores is of great technological importance, because they act as recombination centers for charge carriers in optoelectronic devices. Using hybrid ...

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, ...

Research offers insights into how crystal dislocations -- a common type of defect in materials -- can affect electrical and heat transport through crystals, at a microscopic, quantum mechanical level.

Imperfections of crystal structure, especially edge dislocations of an elongated nature, deeply modify basic properties of the entire material and, in consequence, drastically limit its applications.
