Multiple Schottky Contacts Motivated via Defects to Tune the Response Ability of Electromagnetic Waves

Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 5, 2025

Abstract Metal‐organic framework (MOF) derivatives employed as novel microwave‐absorbing materials (MAMs) have garnered significant attention due to their diverse in situ or ex coordinated components and the flexibility nano‐microstructure fabrication. A well‐designed heterointerface can provide an optimal balance between impedance high‐loss capability. However, precisely tuning semiconductor‐metal‐carbon heterostructures remains a huge challenge. Herein, multi‐component NiS/Co 3 S 4 /NiCo@CNTs/NC nanohybrid with hollow structure is elaborately fabricated using convenient solvothermal method followed by high‐temperature pyrolysis, forming unique heterostructure multiple Schottky contacts. This demonstrates remarkable reflection loss value of −75.9 dB at thickness 2.6 mm. The transcendent microwave absorption (MA) capacity primarily attributed intense polarization relaxation process superb impedance‐matching properties semiconductor/metal/carbon hybrid barriers. In addition, built‐in electric field established heterointerfaces increases electron transport capabilities. Notably, controllable introduction numerous defects into carbon layer intensifies interfacial effect nanohybrid. study offers innovative insights mechanisms development high‐performance MAMs.

Dimensional Design of Cellulose Aerogels with Schottky Contact for Efficient Microwave Absorption

Small, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 5, 2025

Cellulose aerogels, as a novel class of carbon-based materials, exhibit immense potential in the field microwave absorption (MWA) due to their biocompatibility, low density, unique porous structure, and tunable architecture. However, development multi-dimensional components with specialized heterogeneous structures, which are based on cellulose remains significant challenge. This 0D/1D/3D structural configuration facilitates electromagnetic properties favorable impedance matching. The Schottky contact at ZnO/Ni interface, particular, induces strong interfacial polarization, design results multiple heterointerfaces. Density functional theory (DFT) calculations reveal that barrier causes band bending, facilitating directed migration electrons interface formation an internal electric field, thus significantly accelerating multipolar relaxation process. As anticipated, CCMC/ZnO@Ni aerogel exhibits minimum reflection loss (RLmin) value -64.0 dB 13.9 GHz thickness 2.0 mm, its effective bandwidth (EAB) reaches 4.9 GHz. work gives valuable guidance inspiration for materials composed dimensional gradient holds great application wave (EMW) attenuation.
