An anomalous increase of electric conduction with decreasing temperature was found in the current through (Formula presented) epitaxial heterostructures. Comparison with current-voltage characteristics of other ferroelectric epitaxial heterostructures and the analysis using the band diagram indicate that the current is tunneling through the (Formula presented) junction formed by (Formula presented) and (Formula presented) which have been regarded as insulators so far.
