Structural, Dielectric, and Optical Properties of Potassium Tantalate Niobate Thin Films Prepared by Metalorganic Chemical Vapor Deposition


Book Description

The structure-property relations of potassium tantalate niobate (KTaxNb1-xO 3) thin films have been investigated to assess their viability as nonlinear optical materials. Single phase, epitaxial films were deposited by low pressure metalorganic chemical vapor deposition over the entire solid solution range. Under optimized growth conditions, the composition of the films could be controlled within 5 atomic percent.

Ferroelectrics Literature Index


Book Description

Research on ferroelectricity and ferroelectric materials started in 1920 with the discovery by Valasek that the variation of spontaneous polarization in Rochelle salt with sign and magnitude of an applied electric field traced a complete and reproducible hysteresis loop. Activity in the field was sporadic until 1935, when Busch and co-workers announced the observation of similar behavior in potassium dihydrogen phosphate and related compounds. Progress thereafter continued at a modest level with the undertaking of some theoretical as well as further experimental studies. In 1944, von Hippel and co-workers discovered ferroelectricity in barium titanate. The technological importance of ceramic barium titanate and other perovskites led to an upsurge of interest, with many new ferroelectrics being identified in the following decade. By 1967, about 2000 papers on various aspects of ferroelectricity had been published. The bulk of this widely dispersed literature was concerned with the experimental measurement of dielectric, crystallographic, thermal, electromechanical, elastic, optical, and magnetic properties. A critical and excellently organized cpmpilation based on these data appeared in 1969 with the publica tion of Landolt-Bornstein, Volume 111/3. This superb tabulation gave instant access to the results in the literature on nearly 450 pure substances and solid solutions of ferroelectric and antiferroelectric materials. Continuing interest in ferroelectrics, spurred by the growing importance of electrooptic crystals, resulted in the publication of almost as many additional papers by the end of 1969 as had been surveyed in Landolt-Bornstein.

Nanostructures in Ferroelectric Films for Energy Applications


Book Description

Nanostructures in Ferroelectric Films for Energy Applications: Grains, Domains, Interfaces and Engineering Methods presents methods of engineering nanostructures in ferroelectric films to improve their performance in energy harvesting and conversion and storage. Ferroelectric films, which have broad applications, including the emerging energy technology, usually consist of nanoscale inhomogeneities. For polycrystalline films, the size and distribution of nano-grains determines the macroscopic properties, especially the field-induced polarization response. For epitaxial films, the energy of internal long-range electric and elastic fields during their growth are minimized by formation of self-assembled nano-domains. This book is an accessible reference for both instructors in academia and R&D professionals. Provides the necessary components for the systematic study of the structure-property relationship in ferroelectric thin film materials using case studies in energy applications Written by leading experts in the research areas of piezoelectrics, electrocalorics, ferroelectric dielectrics (especially in capacitive energy storage), ferroelectric domains, and ferroelectric-Si technology Includes a well balanced mix of theoretical design and simulation, materials processing and integration, and dedicated characterization methods of the involved nanostructures
