Paper Title:
Growth and Properties of Cubic Potassium Tantalate Niobate Crystals
  Abstract

Cubic KTa1-xNbxO3 single crystals with difference compositions have been grown by Czochralski technique in KTaO3- KNbO3 solid solution system. Growth habit, morphological feature, and other properties of two different composition KTN crystals, KTa0.65Nb0.35O3, and KTa0.63Nb0.37O3 are investigated in this work. The X-ray diffraction (XRD) experimental results show that all crystals belong to cubic phase at room temperature, lattice parameter a is 3.993 and 3.994Å corresponded to the composition of x (Nb) =0.35, 0.37, respectively. HXRD and AFM measurement results show all KTN crystals are in high integrity and good quality. The transmittance spectra of KTN crystals show that the cut off wavelength of KTN crystals decreased with the Nb increasing in the crystal. The dielectric-temperature measurement results shows KTN crystal have optimal performance on Kerr effect at the Currie temperature of the crystal. All the results show that the KTN crystals we grown are in good quality and have a broad application prospects
