Elastic stresses in an ionic crystal and on its surface caused
by a periodic electric charge acting along the surface have been estimated
quantitatively. The elastic stresses have been shown to penetrate
the crystal deeper than electric fields causing them. As a result,
the near-surface dislocations tend to move into the crystal depth.
The predicted effect has been observed in experiment.
