In a recent publication (see title), it was proposed that—instead of the average macroscopic electric field—one should use the local or LORENTZ field inside dielectrics to calculate high-field ionic drift mobilities. This incorrect proposition seems now to start circulating even though it has been clearly shown in the past that the standard equations for ionic conduction in solids are by no way subject to any corrections for local or LORENTZ field effects. It is thus worth to recall some basic… Expand

TLDR
First-principles molecular dynamics simulations for the drift motion of oxygen vacancies show that oxygen vacancies, which are initially ionized by trapping photoexcited hole carriers, can easily migrate under an external electric field, supporting the oxygen vacancy model. Expand
