Growth and electro-elastic properties of K(H_1-xD_x)₂PO₄ single crystals

The elastic, piezoelectric and dielectric constants of K(H_1-xD_x)₂PO₄ crystals (with composition x from 0 to 0.90) were determined using the resonance technique and impedance analysis, respectively. The reasons for the composition dependence of these constants were analyzed based on the variation of the crystal structures resolved by single-crystal X-ray diffraction.

Experimental analysis of overall thermal properties of Nd:La₂CaB₁₀O₁₉ crystals

The thermophysical properties of Nd³⁺-doped La₂CaB₁₀O₁₉ crystals were fully analyzed along the a, b, c, c*, a*, <110> and <110>* crystalline directions. The calculated Jackson factors of a series of observed faces on the crystal show that the liquid-solid interface is a smooth surface when the crystal grows from solution.
