Ferroelectric films

The preparation and properties of ferroelectric films are reviewed. Specifi c attention is directed to ferroelectric films prepared by wet chemical met hods. Emphasis is placed on the microstructure and properties of SBT films for memory applications, and their dependence on chemistry and processing, as well as on the effects of chemistry and processing on the properties of piezoelectric and pyroelectric films. Emphasis is placed on recent results obtained in our laboratories, including modeling of the ferroelectric behav ior of films and experimental results in each of these areas. Also consider ed is the use of ferroelectric films in memory, piezoelectric and pyroelect ric devices of various types, with specific note made of the recently-annou nced use of pyroelectric sensors in automobiles.
