Special Issue Information
Dear Colleagues,
Piezoelectrics/ferroelectrics are an important class of functional materials with applications across diverse fields, including force, light, sound, electricity, and medicine. Over the years, piezoelectric/ferroelectric materials have remained a prominent research topic, driving rapid advancements in their development and broadening their practical applications. For example, lead-free piezoelectrics for sensors/actuators are gradually replacing lead-based ceramics because they offer comparable properties. Ferroelectric materials for energy storage have garnered significant attention due to their high power density and rapid charge–discharge capabilities. Emerging ferroelectrics, such as halide perovskite ferroelectrics, are expanding the ferroelectric family, showing great potential for photoelectric and photovoltaic applications. However, fundamental research aiming at understanding structure–property relationships, enhancing functional performance, achieving balanced development of multifunctionality across varying temperatures and frequencies, and developing emerging piezoelectrics/ferroelectrics remains challenging.
This Special Issue focuses on fundamental research into piezoelectric and ferroelectric materials, covering their synthesis, characterization, properties, calculation, simulation, and applications. The collection aims to highlight innovative strategies for enhancing performance, deepening our understanding of structure–property relationships, exploring new functionalities, and developing emerging piezoelectrics/ferroelectrics. Ultimately, the collection seeks to drive the development of next-generation piezoelectric and ferroelectric materials and devices.
In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:
- Basic principles of piezoelectric/ferroelectric materials;
- The design and synthesis technologies of piezoelectric/ferroelectric materials;
- Studies on the structure–property relationships of piezoelectric/ferroelectric materials;
- Advanced characterization technologies of piezoelectric/ferroelectric materials;
- Piezoelectricity, dielectricity, ferroelectricity, electrostriction, electrocaloric effect, energy storage, and photoelectric/photovoltaic properties of piezoelectric/ferroelectric materials (other related advanced materials are also welcome);
- The hardness, fracture toughness, bending, compression, dislocation, and fatigue failure of piezoelectric/ferroelectric materials (other related advanced materials are also welcome);
- Phase-field simulations, first-principle calculations, and machine learning for piezoelectric/ferroelectric materials;
- Ferroelectric/piezoelectric devices: electronic skin, wearable devices, photoelectric/photovoltaic devices, energy harvesting, capacitor energy storage, generators, displacement actuators, ultrasonic transducers, sensors, memory, etc.
