Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

open access: yesAdvanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Excited State Opto‐Ionic Reservoir Computing in Hybrid Perovskite Electrochemically‐Gated Luminescent Cells

open access: yesAdvanced Materials, EarlyView.
A neuromorphic computing system exploiting opto‐ionic modulation in lead halide perovskite microcrystals demonstrates high‐dimensional reservoir dynamics with diffraction‐limited node resolution. Leveraging ultrafast excited‐state interactions, it achieves efficient computation (800 pJ/node‐operation), robustly distinguishing 4‐bit pulse sequences ...

High‐Performance Air‐Stable Polymer Monolayer Transistors for Monolithic 3D CMOS logics

open access: yesAdvanced Materials, EarlyView.
A fibrillar polymer monolayer with a self‐confinement effect is demonstrated, in which aligned chains parallel the nanofiber axis. Employing a top‐gate CYTOP dielectric, this monolayer transistor achieves high mobility (7.12 cm2 V−1 s−1) and exceptional stability over 1260 days in air.

Handed Magnon Propagation in Easy‐Axis Antiferromagnetic α‐Fe2O3

open access: yesAdvanced Materials, EarlyView.
Coherent excitation and detection of handed magnons are achieved in the easy‐axis antiferromagnet α‐Fe2O3. An external magnetic field lifts the degeneracy between left‐ and right‐handed magnons without affecting their propagation velocity. The Dzyaloshinskii–Moriya interaction and anisotropy modulate their amplitude and damping, enabling intrinsic ...

Phase Engineering of Nanogold: Non‐Close Packed Square Planes in A′B′ Stacking with a 0.5 Å Channel

open access: yesAdvanced Materials, EarlyView.
Gold is well known to adopt the face‐centered‐cubic (fcc) structure. This work presents an unusual non‐close‐packed phase attained in a 40‐atom gold nanocluster, which is in contrast with the close‐packed fcc quasi‐isomer. The non‐compact structure exhibits exclusive square planes in a layer‐by‐layer stacking, hence, possessing a unique 0.5 Å channel ...
