Point defects and long-range order
Andreev A. F.
Point defects in three-dimensional systems exhibit a unique topological characteristic which is associated with the slowness of the decrease of a perturbation of the order parameter and which changes the character of the ordering. The plasticity of crystals which is due to point defects should exist as a thermodynamically equilibrium phenomenon. Fluctuations of the concentration of point defects destroy the equilibrium faceting of crystals. © 7995 American Institute of Physics.
