Dead layers are regions with polarization or permittivity different from that of the bulk part of the film. In 2005, Li et al., the dead layer with a thickness of about 9 Å was measured using angle-resolved X-ray spectroscopy at an interface between Pt/BTO.
15 giu 2016 · To find an effective solution for removing such dead layer effect and improve the polarization properties of the BTO film, we have introduced several types of buffer layers between the LNO electrodes and the BTO film by the atomic-scale simulation.

15 giu 2016 · An interface modification method has been adopted to remove such dead layer effects. Our results show that a LaXO 3 (X = Fe, Co) or YNiO 3 (Y = Sr, Ba) buffer layer can effectively remove the dead layer effect in BaTiO 3 film.

15 mag 2017 · The effects of a dead layer were taken into account in the P-E and C-V responses of the thin film considered as a heterostructure. This investigation can be used for every grown thin film to highlight the effective contribution of the thin film to the overall ferroelectric response.
2 ott 2023 · Nature Materials - Ferroelectric dead layers can form at perovskite interfaces—a major challenge in integrating oxide thin films into devices. Here, by depositing an in-plane-polarized...
