Ferroelectrics: Synthesis, Characterization and Applications

Ferroelectrics are a class of materials characterized by their spontaneous electric polarization, which can be reversed by an external electric field. This property arises from the asymmetric arrangement of atoms within the crystal structure, leading to a permanent electric dipole moment. Ferroelectrics can be found in various ceramics, polymers, and crystals. Their unique behavior is analogous to ferromagnetism in magnetic materials. Ferroelectric materials exhibit high dielectric constants, piezoelectricity, and pyroelectricity, making them valuable for numerous applications. They are integral to non-volatile memory devices, capacitors, sensors, actuators, and electro-optic modulators. Advances in ferroelectric thin films have expanded their use in microelectronics and nanotechnology. This book traces the progress of this field and highlights some of its key concepts and applications. It is a valuable compilation of topics, ranging from the basic to the most complex advancements in the field of ferroelectrics. Its readers would gain knowledge that would broaden their perspective about this vast domain.
