abstract = {A mathematical-physical model to describe the charge
transport across grain boundaries (GBs) in p-type SrTiO3
ceramics under DC load was developed. The model structure
consists of a 1-dimensional cross section through a ceramic
scenario that is bounded by electrodes. After an initial
electrostatic simulation a DC bias voltage step is applied.
The evolution of the spatial profiles of electric potential,
defect concentrations etc., and the current response are
calculated. The results for the ceramic model structure
confirm the experimentally observed Debye relaxation, and
the characteristic dependence of long-term conductivity on
the DC bias after space-charge polarization.},
