AbstractVarious dislocation configurations are examined in the NaCl structure for the presence of localized electrostatic charge assuming slip systems of the {110} 〈110〉 type. Pure edge and screw dislocations do not display an effective electrostatic charge. However, edge dislocations that possess a jog length of a √2/4 or an abrupt kink length of a √2/8 display a virtual charge of ± q/2 whereas edge dislocations that possess a jog length of a √2/2 or an abrupt kink length of a √2/4 are electrically neutral (a is the lattice parameter and q is the ionic charge). Similarly, screw dislocations that possess a jog length of a √2/4 or an abrupt kink length of a/4 display a virtual charge of ±q/2 whereas screw dislocations that possess a jog length of a√2/2 or an abrupt kink length of a/2 are electrically neutral. Either type of jog can be formed on a dislocation, but charged kinks must occur in electrically neutral pairs. Intersection between dislocations on orthogonal slip planes yields only neutral jogs whereas intersection between dislocations on oblique slip planes yields only charged jogs and neutral kinks. Nodes formed by the intersection of n edge dislocations display a virtual charge of ±q/2 whenever n is odd (n ≠ 1) and are electrically neutral otherwise. The emergence point of a dislocation on an atomically flat surface always is neutral although the point may acquire a charge of ±q by ion transport. In general, the presence of a charge of ±q/2 denotes an infinite source (or sink) for anion and cation vacancies whereas a charge of ±q denotes an expendable source.
