Settling a half century of debate, researchers have discovered that tiny linear defects can propagate through a material faster than sound waves do. These linear defects, or dislocations, are what ...

Understanding how dislocations (line defects in the crystal structure) occur when 3D-printing metals has been unclear to materials scientists. Understanding when and how dislocations form in ...

Dislocation dynamics examines the behaviour of line defects within crystalline materials—imperfections that are central to understanding plastic deformation. At the microstructural level, the motion ...

AMES, Iowa – Materials engineers don’t like to see line defects in functional materials. The structural flaws along a one-dimensional line of atoms generally degrades performance of electrical ...

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.

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 ...

Researchers have discovered that engineering one-dimensional line defects into certain materials can increase their electrical performance. Materials engineers don't like to see line defects in ...

(Nanowerk News) Settling a half century of debate, researchers have discovered that tiny linear defects can propagate through a material faster than sound waves do. Dislocations in materials can ...
