Interlayer‐Mediated Stabilization of Metastable P63cm ScFeO3 on Al2O3
Advanced Materials Interfaces, EarlyView.This work develops an interlayer‐mediated stabilization method, demonstrated by the deposition of the P63cm phase of ScFeO3 ‐a metastable polymorph that exhibits multiferroic and optical properties not possible in the ground state. Thin films of the P63cm phase of ScFeO3 are stabilized on (0001) Al2O3 by the spontaneous formation of two atomic layers ...

The Rise of Refractory Transition‐Metal Nitride Films for Advanced Electronics and Plasmonics
Advanced Materials Interfaces, EarlyView.Transition‐metal nitrides (TMNs) are exceptional materials with high stability, biocompatibility, and semiconductor integration, which have been extensively employed in various fields. However, the epitaxial growth of TMN films remains a challenge. The absence of high‐quality TMNs limits the understanding of their condensed matter physics and hinders ...

Phase Engineering for Enhanced Piezoresponse in P(VDF‐TrFE) and Its Composites
Advanced Materials Interfaces, EarlyView.As the temperature approaches the Curie point, the crystalline phase in P(VDF‐TrFE) decreases proportionally, while the amorphous phase increases. This shift leads to the formation of more interphase regions. Although spontaneous polarization from crystalline regions decreases, the interphase regions enable additional deformation, thereby enhancing the
