About. Sections. PDF. Tools. Share. Abstract. Ferroelectric thin films have recently received unprecedented attention due to the need to miniaturize electronic circuit devices. Synthesis and deposition processes along with theoretical calculations are improved remarkably to realize stable ferroelectric thin films up to nanometer thickness.
2. Okt. 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...
15. Juni 2016 · Therefore, the dead layer effect of a ferroelectric thin film can be well addressed. Our results imply that interface engineering is an effective approach to enhance the polarization stability of the ferroelectric thin film and may boost the applications of ferroelectric thin films in modern nano-electronic devices.

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.
Surface dielectric dead layer in ferroelectric perovskite thin films was suggested as an explanation for decrease in effective polarization as the film thickness decreases; however, whether the dead layer exists as a distinct structural feature has long been a subject of scientific debate [1, 2].
