Ferroelectricity in Single‐Crystalline BaTiO3 Nanodisks on Silicon
Advanced Functional Materials, EarlyView.Ferroelectricity is studied in 20 nm thick single crystalline BaTiO3 nanodisks when scaling their diameter from ≈ 400 down to 100 nm. For 100 nm diameter, the vertical polarization component adopts three distinct patterns, and the lateral one shows a rotational invariance in‐plane, suggesting a combination of center‐type and flux‐closure domains.

Advanced Functional Materials, EarlyView.Spinal cord injury (SCI) poses significant challenges for regeneration due to a series of secondary injury mechanisms. How to use biomaterial approach to target the failed regeneration after SCI remains a critical challenge. This review systematically evaluates current strategies to optimize biomaterial topographies for neurite outgrowth, axonal ...

Importance of second-order piezoelectric effects in zincblende semiconductors
, 2006 We show that the piezoelectric effect that describes the emergence of an electric field in response to a crystal deformation in III-V semiconductors such as GaAs and InAs has strong contributions from second-order effects that have been neglected so far.

Advanced Functional Materials, EarlyView.A scalable biomimetic platform transforms bioinert poly(ethylene glycol) diacrylate into neuroinstructive matrices via integrating solvent transfer‐induced phase separation, microfluidics, and 3D bioprinting. Bicontinuous, hyperbolically curved microporous networks embedded within a fibrous construct elicit rapid adhesion, robust proliferation, and ...

Advanced Functional Materials, EarlyView.Charge carrier concentration and mobility in TiO2, ZrO2, and HfO2 powder films are experimentally mapped as a function of temperature. The results uncover polaron‐mediated transport regimes and field‐activated conduction, enabling the design of oxide‐based electronic and energy devices with thermally tunable functionality.

Domain Nucleation and Growth in an Epitaxially Grown Wurtzite Ferroelectric
Advanced Functional Materials, EarlyView.Ferroelectric domain nucleation and growth in epitaxial wurtzite (Al, B, Sc)N films are visualized through in situ transmission electron microscopy. Domains initiate near the bottom electrode and propagate laterally with zigzag walls, while unswitched regions remain near the electrode interfaces.
