By studying the time dependence of the current flowing through undoped BaTiO3, we have examined whether the conductivity peaking is due to a real conduction or to the fake current caused by ferroelectric domain switching. The difference (ΔQ) between integrated current at temperatures (388K and 400K) above and below TC exceeds the charge which can be released by domain switching. This result shows that conductivity peaking is indeed due to real conduction.
