Abstract
Single crystals of KYbxY1-x(WO4)2 of high optical quality were grown at a rate of about
4.0 mm/day by the modified Czochralski method. The crystals have been grown using the so-called dynamic growth regime. The optimal temperature gradients have been determined at the crystallization front. Thermal expansion coefficients of KYbxY1-x(WO4)2 are determined in the directions of the optical indicatrix axes Np, Nm and Ng in the temperature range of 60 – 300 °C using dilatometric technique.
期刊介绍：
The journal offers a common reference and publication source for workers engaged in research on the experimental and theoretical aspects of crystal growth and its applications, e.g. in devices. Experimental and theoretical contributions are published in the following fields: theory of nucleation and growth, molecular kinetics and transport phenomena, crystallization in viscous media such as polymers and glasses; crystal growth of metals, minerals, semiconductors, superconductors, magnetics, inorganic, organic and biological substances in bulk or as thin films; molecular beam epitaxy, chemical vapor deposition, growth of III-V and II-VI and other semiconductors; characterization of single crystals by physical and chemical methods; apparatus, instrumentation and techniques for crystal growth, and purification methods; multilayer heterostructures and their characterisation with an emphasis on crystal growth and epitaxial aspects of electronic materials. A special feature of the journal is the periodic inclusion of proceedings of symposia and conferences on relevant aspects of crystal growth.
