Abstract

Here we correct the boundary conditions to clarify confusing statements that appeared in the original article. Namely, the boundary condition (5) is redundant and must be omitted. For solving the Cauchy problem, which is Eqs. (1) and (3), the boundary condition, Eq. (4), is sufficient together with initial conditions for the field and defect concentration mentioned immediately after Eq. (1). Applying another constraint, like Eq. (5), would lead to a contradictory overdefinition of the problem. Also, Eq. (5) is followed by the statement that the z-component of the electric field at the grain boundary remains constant, TtEz(x,0,t)=0, which is not correct. In fact, the condition (5) was not used in the calculations of Section III, where the field was evaluated explicitly from the formulas (19-22). Thus, all the analytical and numerical results and conclusions presented in the paper remain valid irrespective of the corrections given here.
