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 ...

Reducing defects on the wafer edge, bevel, and backside is becoming essential as the complexity of developing leading-edge chips continue to increase, and where a single flaw can have costly ...

This article summarizes some of the defects seen during GaN wafer processing and the characterization techniques that can be used to detect them. Gallium nitride (GaN) offers many intrinsic material ...

(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 ...

Abstract: Dislocation movement is closely related to the plastic deformation behavior of crystals, and the reaction between lattice slip dislocations and grain boundaries plays an important role in ...

When a material fails, it can have devastating consequences – making bridges collapse or pipelines explode. Tomas Martin and Stacy Moore describe how innovative and complementary microscopy and ...

Abstract: Amorphization commonly occurs during implantation forming end of range (EOR) defects at the amorphous/crystal line (a/c) interface upon annealing. It is imperative to know how these defects ...

Dislocations—the carrier of plastic deformation—are responsible for a wide range of mechanical properties of metals or semiconductors. Those line-like objects tend to form complex networks that are ...
