“…Shirokov et al employed BST65 thin films to study the relationship between material constants, the applied planar field, and lattice misfit strain in paraelectric phase [124]. When BST65 thin films are affected by constant electric field, a range of misfit strains can lead to significant changes of the material constants.…”

“…When BST65 thin films are affected by constant electric field, a range of misfit strains can lead to significant changes of the material constants. The lattice difference can be tuned by changing deposition temperatures, which may promote film strain engineering for applications [124]. By selecting substrate materials and film with different lattice and different thermal expansion coefficients, the misfit strain can be adjusted to optimize the properties of the film.…”

Artificially-structured functional materials (AFMs) are artificial media that combine the advantages of nature materials and artificial structures to produce excellent and unexpected properties. Ferroelectric materials have key features in possessing spontaneous polarizations, which can be switched by using electric field, temperature, and strain. This review article attempts to provide a comprehensive insight into the current development of ferroelectric composite AFMs, and to introduce a developing subject in realizing multifield controls for tunable functional devices. Some typical ferroelectric materials and their multifield tunable mechanisms are summarized in detail. The incorporation of ferroelectric materials can yield various designs of AFMs to modulate electromagnetic waves. Recent progress of typical designs with different tuning strategies for active AFMs are illustrated and compared, including the metamaterials, metasurfaces, heterojunctions, superlattices, and their hybrid designs. This scientific subject involves interesting research topics of electromagnetism, electronics, optoelectronics, and ferroelectrics, which is significant to bring novel functionalities via multifield controls.
