In this paper, the dead layer existed in surface-induced relaxation Pt/BTO interfaces, and the relaxation layer present at this interface had different properties from bulk BTO. The dead layer is also formed by chemical intermixing between the electrode and the ferroelectric film.
2. Okt. 2023 · 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 epitaxial buffer layer...
23. März 2000 · Extensive studies have shown that this phenomenon could be caused by a ‘dead layer’ of very low dielectric constant between the ferroeletric film and the electrode 2,3.

15. Juni 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.

12. Okt. 2006 · New theoretical work nails down the microscopic origin of 'dead layers' in nanometre-scale capacitors and demonstrates that it is an intrinsic effect. The results provide practical guidelines...

23. Dez. 2020 · In this study, we investigate the effects of various electrodes on the ferroelectric properties of ultrathin HfZrO x (HZO) films. The ferroelectric polarization is totally suppressed in the HZO films with TiN and W bottom electrodes when the film thickness is below 5 nm.
12. März 2009 · This dramatic drop in capacitance is attributed to the so-called “dead layer”—a low-permittivity layer at the metal-dielectric interface in series with the high-permittivity dielectric. The exact nature of the dead layer and the reasons for its origin still remain somewhat unclear.
