Tunable and Persistent Macroscopic Polarization in Nominally Centrosymmetric Defective Oxides

Advanced Materials, Volume 38, Issue 3, 13 January 2026.
This work introduces an approach to defect‐mediated symmetry breaking and built‐in polarization in nominally centrosymmetric defective oxides, Gd‐doped CeO2‐δ films, by controlling macroscopic charge asymmetry. Electric field‐driven asymmetric redistribution of oxygen vacancies induces a switchable, stable polarization, leading to a notable, persistent

Microstructure Optimization via Grain‐Boundary Segregation to Enhance DC Bias Dielectric Performance of BaTiO3 Multilayer Ceramic Capacitors

Advanced Materials, Volume 38, Issue 1, 2 January 2026.
By tuning grain size through nanoscale grain‐boundary segregation of single‐element additives, high‐performance BaTiO₃‐based multilayer ceramic capacitors (MLCCs) exhibit exceptionally low dielectric loss over a wide frequency range and excellent thermal stability.

Colossal Cryogenic Electro‐Optic Response Through Metastability in Strained BaTiO3 Thin Films

Advanced Materials, Volume 38, Issue 3, 13 January 2026.
Utilizing the thermodynamic theory of optical properties, a colossal cryogenic electro‐optic response in BaTiO3 thin films is designed and demonstrated by stabilizing a low symmetry metastable monoclinic phase via epitaxial strain tuning with an electro‐optic response reaching ≈2516 pm V−1 at 5 K. This approach represents a new paradigm for engineering

Temporally Reconfigurable Reservoir Computing with Flexible Electrolyte‐Gated TFTs for High‐Performance Neuromorphic Processing

Advanced Materials, Volume 38, Issue 1, 2 January 2026.
A temporally reconfigurable reservoir computing system is developed using ultrathin, flexible, all‐solid‐state electrolyte‐gated thin‐film transistors (UFLEX TFTs). By simply tuning temporal dynamics electrically, the system achieves 93.7% accuracy for MNIST handwritten digits, 90.3% for CIFAR‐10 images, and 81.8% for chest X‐rays, surpassing CNNs in ...

Strain‐Engineered Monolithic Multi‐Band LEDs for Simultaneous Short‐Wavelength and Mid‐Wavelength Infrared Emission

Advanced Materials, Volume 38, Issue 3, 13 January 2026.
A monolithic multi‐band LED capable of simultaneously emitting short‐ and mid‐wavelength infrared light is demonstrated, enabled by Sb doping–driven strain engineering that achieves balanced strain compensation and coherent epitaxy in the quantum wells.
