Monolithic UV‐Laser Programming of Photothermally Meta‐Morphing SMA Structures: Dual‐Encoded Kirigami Mechanics and Photonic Absorbance

open access: yesAdvanced Science, EarlyView.
A monolithic manufacturing strategy is presented for photothermal shape memory alloy (SMA) meta‐morphing structures. Using a single‐step UV‐laser process, the mechanical compliance is programmed via kirigami patterning while optical absorbance is simultaneously tuned through surface oxidation.

Structurally Enhanced Colloidal Molecules via Carbene‐Mediated Covalent C─H Insertion Crosslinking

open access: yesAdvanced Science, EarlyView.
This work presents a nonspecific covalent crosslinking strategy to significantly enhance the structural stability of colloidal molecules (CMs) without compromising their inherent structural and physicochemical properties by rationally designing a diazo‐based crosslinker.

Quantifying Strain and Its Effect on Charge Transport in Ge/Si Core/Shell Nanowires

open access: yesAdvanced Science, EarlyView.
This work demonstrates strain engineering in Ge/Si core–shell nanowires (CS NWs) by tuning the Ge core‐Si shell dimensions. Polarization‐resolved µ‐Raman and geometrical phase analysis quantify the resulting strain. Electronic transport measurements demonstrate record hole mobilities up to 25 400 cm2/Vs, highlighting these Ge/Si CS NWs as a promising ...

Proximity Ferroelectricity in Compositionally Graded Structures

open access: yesAdvanced Electronic Materials, EarlyView.
We perform the finite element modeling of the polarization switching in the compositionally graded AlN‐Al1‐xScxN and ZnO‐Zn1‐xMgxO structures and reveal the switching of spontaneous polarization in the whole structure in all these systems. The coercive field to switch is significantly lower than the electric breakdown field of the unswitchable AlN and ...

Exceptional Antimodes in Multi‐Drive Cavity Magnonics

open access: yesAdvanced Electronic Materials, EarlyView.
Driven‐dissipative cavity‐magnonics provides a flexible platform for engineering non‐Hermitian physics such as exceptional points. Here, using a four‐port, three‐mode system with controllable microwave interference, antimodes and coherent perfect extinction (CPE) are realized, enabling active tuning to antimode exceptional points.
