Ultralow‐Frequency Epsilon‐Near‐Zero States in 3D‐Printed High‐Entropy Alloy Metacomposites for Ultra‐Thin Perfect RF Absorption

open access: yesAdvanced Materials, EarlyView.
Rozanov causality limit—a compulsive proportional thickness‐wavelength relationship (nd ∝ λ)—makes it challenging to develop perfect absorption with both thin thickness and low frequency. Herein, a cocktail effect in high‐entropy alloys (HEA) is crucially utilized for lowering plasma frequency to achieve epsilon‐near‐zero states, which finally enables ...

Photo‐Reconfigurable Supercoupling Induced Transparency in On‐Chip Topological Edge State Cavities

open access: yesAdvanced Materials, EarlyView.
A novel supercoupling induced transparency (SIT) is demonstrated in a valley‐Hall photonic crystal. The valley vortices enable the supercoupling between a leaky and a guided topological edge state cavity even across a distance of 4.3 wavelengths, inducing a transparency window with negligible reflection.

Engineering Free Volume within Frontal Ring‐Opening Metathesis Polymerization via Pendant Plasticization

open access: yesAdvanced Materials, EarlyView.
Norbornene‐based copolymers with tunable n‐alkyl pendant length provide control over matrix free volume, enabling elastomeric materials via frontal ring‐opening metathesis polymerization (FROMP). ABSTRACT Frontal ring‐opening metathesis polymerization (FROMP) enables rapid, energy‐efficient access to high‐performance thermosets and thermoplastics, but ...

Ultrathin Monatomic Antimony Films by Sacrificial Atomic Layer Deposition for Phase Change Memory

open access: yesAdvanced Materials, EarlyView.
A three‐step sacrificial atomic layer deposition (s‐ALD) process enables wafer‐scale growth of ultrathin and uniform antimony (Sb) thin films. An ultrathin (≈4 nm) Sb film is uniformly deposited with its characteristic bilayer structure (Sb‐Sb) aligned along the substrate.
