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

where b is the Burgers vector and D is the inter-dislocation spacing. · For the tilt boundary shown, the dislocations are straight edge type. For a pure twist boundary, an array of screw dislocations ...

· The Mixed dislocations is the most general type of unit dislocation and has an arbitrary angle between its line vector and Burgers vector. b is a constant of the dislocation. · The dislocation line ...
