Published in 2025 at "Advanced Functional Materials"

DOI: 10.1002/adfm.202505381

Abstract: Constructing built‐in electric fields is a proven method to enhance dielectric loss mechanisms by amplifying interfacial polarization. However, a single built‐in electric field is often insufficient for significantly improving electromagnetic (EM) polarization loss. To address… read more here.
