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.

Dislocation dynamics form the cornerstone of our understanding of plastic deformation in crystalline metals and alloys. These line defects traverse crystallographic planes under applied stress, giving ...

In the quest to optimize the efficiency of materials, attention is increasingly focused from the nanoscale to understanding how microscale defects, such as stacking faults and dislocations, affect the ...

Researchers have dived down to the atomic scale to resolve every 'jiggle and wiggle' of atomic motion that underlies metal strength. Lawrence Livermore National Laboratory researchers have dived down ...

Dislocations can save lives. This stems from the fact that the one-dimensional defects in a metal play an important role when the material deforms: for example, when a car body panel crumples in an ...

Illustration of an intense laser pulse hitting a diamond crystal from top right, driving elastic and plastic waves (curved lines) through the material. The laser pulse creates linear defects, known as ...

An international team of researchers, led by University of Toronto Engineering Professor Yu Zou, is using electric fields to control the motion of material defects. This work has important ...

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.

Lawrence Livermore National Laboratory researchers have dived down to the atomic scale to resolve every "jiggle and wiggle" of atomic motion that underlies metal strength. In a first of its kind ...
