      abstract     = {Electronic tunneling through ferroelectric insulators is
                      considered to be a key ingredient of future oxide
                      electronics. We investigate the role of the electronic band
                      structure of the decaying electronic states in the band gap
                      by first discussing the expected behavior of tunneling in
                      the effective mass model. We demonstrate that, even for the
                      simple prototype ferroelectric oxides in the perovskite
                      structures PbTiO3 and BaTiO3, the basic assumption of the
                      effective mass model is not appropriate, and that the
                      correct interpretation of tunneling in these materials
                      requires a material-specific description of the evanescent
                      states as provided by the complex band structure.},
