Realization of Non‐Equilibrium Wurtzite Structure in Heterovalent Ternary MgSiN2 Film Grown by Reactive Sputtering

Advanced Electronic Materials, EarlyView.
The piezoelectric and ferroelectric applications of heterovalent ternary materials are not well explored. In this study, c‐axis‐oriented epitaxial MgSiN2 films with the wurtzite structure are successfully grown on (111) Pt//(001)Al2O3 substrates by reactive RF magnetron sputtering at 600 °C under pure N2 atmosphere.

Machine‐Learning‐Assisted Understanding of Depth‐Dependent Thermal Conductivity in Lithium Niobate Induced by Point Defects

Advanced Electronic Materials, EarlyView.
Thermal conductivity, a fundamental property of lithium niobate, plays a pivotal role in determining its device performance. By integrating experiments with machine‐learning‐assisted simulations, this study demonstrates that oxygen vacancies induced by thermal reduction result in a pronounced suppression of thermal conductivity and a marked depth ...

High‐Quality Epitaxial Five‐Layer Aurivillius Films with In‐Plane Ferroelectricity for Electrocaloric Cooling

Advanced Electronic Materials, EarlyView.
High‐quality epitaxial five‐layer Sr2Bi4Ti5O18Aurivillius films are grown on SrTiO3 by pulsed laser deposition. The electrocaloric effect derived from measurements of the in‐plane ferroelectric polarization reveals a maximum temperature change of ΔT ∼ 0.95 °C under an electric field of 150 kV cm⁻¹ at 135 °C.

All‐Electric Mimicking of Synaptic Plasticity Based on the Noncollinear Antiferromagnetic Device

Advanced Electronic Materials, EarlyView.
Mn3Pt was chosen as spin source with a simple face‐centered cubic structure and a noncollinear antiferromagnetic configuration to build a spin‐orbit torque (SOT) device that mimics all‐electric synaptic behavior for developing neuromorphic computing.
