Dielectric Property of a Large‐Scale Transferred Single‐Crystal BaTiO3 Film Prepared Using a Water‐Soluble Sacrificial Buffering Layer

open access: yesAdvanced Materials Interfaces, EarlyView.
A large‐scale single‐crystal BaTiO3 thin film is successfully transferred to a PET substrate using Ba‐doped Sr3Al2O6 water‐soluble sacrificial layer, which reduces the mismatch strain between the objective film and the substrate. The high crystallinity of BaTiO3 is maintained during the transfer process, and a very low dielectric loss (tanδ < 0.1) of ...

Electrically reversible cracks in an intermetallic film controlled by an electric field

open access: yesNature Communications, 2018
Electric-field-induced cracks are generally detrimental to functionality of ferroelectric ceramics. Liu et al. use an intermetallic alloy and ferroelectric oxide junction to mediate the reversible formation of cracks at nanoscales, resulting in colossal ...

Freestanding TiN‐Au Vertically Aligned Nanocomposite Thin Films for Flexible Plasmonic Hybrid Metasurfaces

open access: yesAdvanced Materials Interfaces, EarlyView.
Freestanding TiN–Au vertically aligned nanocomposite (VAN) thin films are fabricated by dissolving a Sr3Al2O6 sacrificial layer and releasing from the substrates. Freestanding VAN films combine flexibility with strong plasmonic resonance properties, providing a versatile platform for future applications in flexible photonics, plasmonics, and integrated

Modelling of Pyroelectric Response in Inhomogeneous Ferroelectric-Semiconductor Films [PDF]

open access: yes, 2005
We have modified Landau-Khalatnikov approach and shown that the pyroelectric response of inhomogeneous ferroelectric-semiconductor films can be described by using six coupled equations for six order parameters: average displacement, its mean-square ...

Photostrictive materials

open access: yes, 2015
Light-matter interactions that lead to nonthermal changes in size of the sample constitute a photostrictive effect in many compounds. The photostriction phenomenon was observed in four main groups of materials, ferroelectrics, polar, and non-polar ...
