Characterization and visualization of the lattice misfit associated with dislocation cores

Atomic misfit associated with a crystal dislocation is manifested by displacements of atoms from their positions in the perfect lattice. The discrete character of the crystal lattice and the nature of interatomic bonds distribute this misfit over the plane normal to the dislocation line. The Nye tensor, which describes the distribution of the resultant Burgers vector across a plane normal to the dislocation line, provides an excellent means of...
