Magnetic-Dielectric Heterojunctions Regulation in Ni-MnO/C Microspheres With Tunable Electromagnetic Wave Absorption.
Heterojunctions engineering is crucial for optimizing dielectric polarization and electromagnetic (EM) wave absorption, yet precise spatial control over semiconductor components in magnetic-dielectric microspheres remains challenging. Herein, super-dispersed MnO protrusions and Ni particles were confined within a carbo...
