Über dieses Buch

Springer-Verlag, Berlin Heidelberg, in conjunction with Springer-Verlag New York, is pleased to announce a new series: CRYSTALS Growth, Properties, and Applications The series presents critical reviews of recent developments in the field of crystal growth, properties, and applications. A substantial portion of the new series will be devoted to the theory, mechanisms, and techniques of crystal growth. Occasionally, clear, concise, complete, and tested instructions for growing crystals will be published, particularly in the case of methods and procedures that promise to have general applicability. Responding to the ever-increasing need for crystal substances in research and industry, appropriate space will be devoted to methods of crystal characterization and analysis in the broadest sense, even though reproducible results may be expected only when structures, microstructures, and composition are really known. Relations among procedures, properties, and the morphology of crystals will also be treated with reference to specific aspects of their practical application. In this way the series will bridge the gaps between the needs of research and industry, the pos­ sibilities and limitations of crystal growth, and the properties of crystals. Reports on the broad spectrum of new applications - in electronics, laser tech­ nology, and nonlinear optics, to name only a few - will be of interest not only to industry and technology, but to wider areas of applied physics as well and to solid state physics in particular. In response to the growing interest in and importance of organic crystals and polymers, they will also be treated.

The Growth of Synthetic and Imitation Gems
Abstract
Verneuil successfully duplicated natural ruby at the turn of the century. Since then, diamond, emerald, blue and other color sapphires, quartz (including the amethyst and citrine varieties), spinet, and chrysoberyl have been added to the list of single crystals used as synthetic gems. Crystals such as rutile, strontium titanate, YAG, GGG, and cubic zirconia have also been used as diamond imitations. More recently, non-single crystal materials such as opal and turquoise have also been synthesized.

The Growth of Large Crystals from the Vapor Phase
Abstract
The article demonstrates various methodes which lead to large single crystals from the vapor phase. The term “large” means that the size of the crystal is determined by the stock of the source material only. The discussions are restricted to the growth of crystals which evaporate congruently, although the described methods can be used for dissociative sublimation or chemical transport as well.

Crystal Growth from the Melt
Experimental Investigation of Kinetics and Morphology
Abstract
Data on kinetics, morphology and mechanisms of crystal growth from the melt, based on the authors’ experimental investigations of a vast variety of substances, are presented and related to the value of the melting entropy. Experimental evidence has been obtained in favor of rough interface models of crystal growth. Distinctive features of such phenomena as the evolution of crystal shapes with the supercooling of the melt, the stability of growth shapes, the capture of impurities and their influence on crystal growth have been stated for low- and high-entropy substances.

Morphology and Physical Properties of Gamma Iron Oxide
Abstract
Gamma ferric oxide, γ-Fe2O3, is still the most widely used material for magnetic recording devices. Although there are literature references dating in the 19th century, the material was virtually unknown until systematic studies were commenced about 1925. Methods to prepare small, polycrystalline particles of various shapes, both unsupported and supported on iron metal, as well as epitaxial single-crystal films, are indicated. Data on the crystallographic and magnetic structure and other physical properties are summarized. The transformations from magnetite to gamma ferric oxide to hematite are treated. Finally, γ-Fe2O3 with other cation substitutions is considered. Some directions where further research is needed are suggested.
