We might imagine crystals to be perfect structures, but they are, in fact, often plagued with "defects." Curiously enough, such defects often appear due to atoms undergoing reorganization to lower the ...

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 ...

Materials scientists at Rice University have developed a new workflow methodology for measuring microscopic defects in ...

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.

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 ...

Building large-scale quantum technologies requires reliable ways to connect individual quantum bits (qubits) without destroying their fragile quantum states. In a new theoretical study, published in ...

The diagram shows the effect of 'sliding' an Edge (a), Screw (b), or Mixed (c) dislocation completely across a slip plane in the crystal. Each dislocation has the same effect as it moves completely ...

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 ...
