Designer Moiré Quantum Materials Enabled by Freestanding Oxide Membranes in Twisted and Hybrid Bilayers

open access: yesAdvanced Science, Volume 13, Issue 58, 19 October 2026.
Freestanding oxide membranes transform twistronics by enabling deterministic stacking, strain release, and integration with two‐dimensional materials. A unified framework links local atomic registry to structural reconstruction, polar textures, charge modulation, flat bands, and magnetic responses, while identifying the fabrication and characterization

Engineering a Correlated Narrow‐Gap Semiconductor: Effects of Ga Substitution in EuZn2P2

open access: yesAdvanced Electronic Materials, Volume 12, Issue 19, 12 October 2026.
ABSTRACT The effect of Ga substitution on the electronic, magnetic, and low‐energy responses of the Zintl phase EuZn2P2${\rm EuZn}_2 {\rm P}_2$ is investigated by electrical transport, electron spin resonance (ESR), and terahertz time‐domain spectroscopy (THz‐TDS). Incorporating Ga into EuZn2P2${\rm EuZn}_2 {\rm P}_2$ (EuZn1.8Ga0.2P2${\rm EuZn}_{1.8} {\

Synthesis and Properties of Semiconductor BaTiO3 with a Colossal Dielectric Permittivity

open access: yes, 2017
Microstructure, crystal parameters, and electrophysical properties of dielectric and semiconductor ceramics based on barium titanate were investigated over a wide frequency range. Contributions of different mechanisms of polarization in the value of the dielectric permittivity of the samples were determined.

Nonlinear Force‐Extension Response of a Polyelectrolyte Chain Undergoing Mechano–Electrostatic–Conformational Coupling and Metastable Heterogeneity

open access: yesSmall Structures, Volume 7, Issue 9, September 2026.
Mechanical stretching drives a collapsed polyelectrolyte through globular, tadpole‐like, and extended conformations with concurrent charge redistribution. Counterion condensation neutralizes the compact head, whereas release sustains a highly ionized tail.

Field‐Frustrated Cooperative Distortions: Suppressing Jahn‐Teller Ordering via Microwave Annealing

open access: yesAdvanced Science, Volume 13, Issue 48, 28 August 2026.
Microwave annealing decouples local Jahn‐Teller distortions from long‐range cooperative ordering in CuFe2O4, stabilizing a metastable cubic phase that remains locally distorted yet globally symmetry‐frustrated. Synchrotron XRD, PDF, XPS, and in situ thermal cycling reveal how non‐equilibrium MW‐phonon interactions suppress cooperative orbital‐lattice ...
