ACCORDING to the theory of Burton, Cabrera and Frank 1, crystals can only grow at supersaturations too low for two-dimensional nucleation, when dislocations are present. Where a screw dislocation ...
In 1949 Frank 1,2 pointed out the possibility that growth of crystals at low supersaturations, essential for good crystals, could take place because of the formation of dislocations in the crystal so ...
(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 ...
