Abstract

We study the leading mechanisms of kink mobility of 30° and 90°-partial dislocations in the glide set {111} of silicon. The calculations are performed using a new empirical potential for Si, which has been shown to give an accurate description of core properties of partial dislocations [1], to study mechanisms of kink formation and migration. In the case of 30°-partial dislocation, two kinds of kinks are identified, left and right, which have different structures, formation energies, and mobilities.
