For nearly a century, scientists have understood how crystalline materials—such as metals and semiconductors—bend without ...

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 ...

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.

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.

A crystalline material such as gold undergoing a permanent change in shape when loaded mechanically is the result of crystal plasticity. The scientific inquiry for the ideal strength against plastic ...
