Addendum: Dislocations and the piezoelectric effect in III–V crystals

The erroneous assumption that for an insulating crystal the electrical displacement field (?) is zero in the absence of an applied electrical field has led to wrong values for the line charges associated with dislocations as well as for the electric fields and core charges associated with point defects in III-V crystals. The values for the charge distribution associated with these two types of defects are, however, not affected.
