Screw dislocations play an important role in materials’ mechanical, electrical and optical properties. However, imaging the atomic displacements in screw dislocations remains challenging. Although ...
Researchers show that Cartan's First Structure Equation, which relates to edge and screw dislocations in crystal lattices, can be recast in the same form as a basic mathematical formula that governs ...
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 ...
