(Nanowerk News) Researchers from the University of Rostock and Technion Haifa have created the first three-dimensional topological insulator for light. A judiciously placed screw dislocation allows ...

In this paper, we consider dislocations in the framework of first as well as second gradient theory of elasticity. Using the Fourier transform, rigorous analytical solutions of the two-dimensional ...

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 ...
