Functional Dielectrics for Electronics: Fundamentals of Conversion Properties presents an overview of the nature of electrical polarization, dielectric nonlinearity, electrical charge transfer mechanisms, thermal properties, the nature of high permittivity, low-loss thermostability and other functional dielectrics. The book describes the intrinsic mechanisms of electrical polarization and the energy transformations in non-centrosymmetric crystals that are responsible for converting thermal, mechanical, optical and other impacts into electrical signals. In addition, the book reviews the main physical processes that provide electrical, mechanoelectrical, thermoelectrical and other conversion phenomena in polar crystals.
Detailed descriptions are given to electrical manifestations of polar-sensitivity in the crystals, the interaction of polarization with conductivity, the anomalies in thermal expansion coefficient and main peculiarities of heat transfer in polar-sensitive crystals.
The dielectrics intended for use in electrical and electronic devices must have good electrical insulating properties, including very low electrical conductivity and high electrical strength. At the same time, in present-day electronics technology, other properties of dielectrics have gained special importance, namely those that allow for conversion of energy or information; these dielectrics may be considered functional materials.
The functional (or active, or adaptive, or controlled, or smart) dielectrics actively react to changes of temperature, pressure, mechanical stress, electrical and magnetic fields, light illumination, and even smell. Functional dielectrics can be classified as pyroelectrics, ferroelectrics, piezoelectrics, electrets, quantum-electronics materials, microwave dielectrics with tunable permittivity, etc.
Provides readers with a fundamental understanding of polar dielectric materials and their physical processes Includes different models of polar sensitivity and experimental confirmation of these models Discusses thermal expansion, heat transfer, dielectric nonlinearity and other important aspects for electronics applications
