Abstract: The kinetics of kink pair formation on dislocations is described within the framework of a model intermediate between the sharp kink model and the continuum elastic string model. The effects resulting from the discrete structure of crystalline materials are considered. The theory is based on the universal Frenkel–Kontorova model and can be applied to extended systems of various natures.

Keywords: dislocation kinks, peierls barriers, Frenkel–Kontorova model, energy landscape.
