Advanced Functional Materials, EarlyView.Significant nanoscale oxygen diffusion coefficient variations are measured in ferroelectric hafnium zirconium oxide films with grain boundaries and electrode interfaces exhibiting values 104 times larger than the grain cores. Overall coefficients are 10X larger for films prepared with metal nitride electrodes compared to refractory metals. New insights

Relative permittivity in stern and diffuse layers.
Acta chimica Slovenica, 2014 Stern layer and outer Helmholtz plane (i.e. the distance of closest approach) are considered within electric double layer models, where the orientational ordering of water dipoles is explicitly taken into account. It is shown that permittivity of the Stern layer is not independent of the surface charge density as it is frequently assumed in different ...

Relative Permittivity of Stockmayer-Type Model Fluids from MD Simulations and COFFEE
, 2022 The relative permittivity is a property that depends on the orientation structure of a fluid. Thus, using state-of-the-art equations of state it can be modeled only when using high level techniques, such as nonprimitive models.

Optical Signature of Moiré Superlattices Formed by Twisted SrTiO3 Membranes
Advanced Functional Materials, EarlyView.We discover optical signatures from bonded interfaces in twisted SrTiO3 moiré superlattices, including low‐frequency Raman vibrational modes and strong second‐harmonic generation, consistent with strong interlayer coupling inferred from cross‐sectional electron microscopy and ab initio calculations. ABSTRACT Moiré superlattices formed at the interfaces

Advanced Functional Materials, EarlyView.Ferroelectric nanoclusters create local internal fields in a normally non‐switchable polar film because of polarization mismatch at their interfaces. That field opposes polarization in the regions with larger polarization and reinforces polarization in the regions with smaller polarization.
