The kink mechanism of dislocation motion in materials with high Peierls-Nabarro barriers of the first and second type was studied. The form of the deviation of the temperature dependence of the kink-formation rate (from the Arrhenius law), caused by the effect of quantum tunnelling upon the formation and migration of kinks was analyzed.

Violation of the Arrhenius Law for the Kink Formation Velocity at Low Temperatures. B.V.Petukhov: Kristallografiya, 1995, 40[3], 433-7 (Crystallography Reports, 1995, 40[3], 393-7)
