Ferroelectric materials are a class of materials that exhibit a spontaneous electric polarization that can be reversed by an external electric field. This unique property makes them attractive for a wide range of applications, including non-volatile memory devices, capacitors, sensors, actuators, and transducers. Research in this area aims to understand the fundamental physics of ferroelectricity, develop new materials with improved properties, and explore novel applications for these materials. Recent advances in ferroelectric materials have led to the development of new technologies with potential for significant impact in various fields.
