Shape of hollow dislocation cores: anisotropic surface energy and elastic effects

Equilibrium morphologies are frequently determined by a competition between interfacial and elastic energies. Holes at the cores of dislocations in materials with large Burgers vectors are a prime example of this type of competition because their existence is solely due to this type of competition....
