Dislocation Motion in an Electric Field

Resumo

An expression for the effective polarization electric charge per unit length of dislocation is obtained. It is shown that the polarization electric charge arises due to the interaction of an electric field only with the edge components of dislocations. An expression is obtained for the force that acts on a dislocation in the electric field and it is shown that the determining role in experiments would be played by the projection of this force onto the dislocation slip plane.
