ZnAl 2 O 4 –ZnO heterostructured nanocomposite with giant dielectric permittivity and epsilon-negative response: frequency- and temperature-dependent dielectric behavior
Year: 2026
Type: article
Abstract: @ZnO heterostructured nanocomposite architecture provides strongly tunable dielectric behavior, spanning giant positive permittivity at low frequencies and elevated temperatures to negative-permittivity response in the MHz regime. While these dielectric characteristics may be of interest for future investigations of temperature-stable capacitive components and electromagnetic structures, device-level performance, including RF resonators, electromagnetic shielding, metamaterials, and ENZ devices, was not directly evaluated in the present work.
