Abstract
An anomalous increase of electric conduction with decreasing temperature was found in the current through 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 junction formed by and which have been regarded as insulators so far.
