Single crystals of cadmium thiourea acetate (CTA) were grown by slow evaporation solution growth technique. The spectral properties of the crystals were studied by FTIR, FT-Raman and factoral group analyses, The structural perfection and growth features of the grown crystals were analysed by high-resolution X-ray diffraction (HRXRD) and wet chemical etching studies, respectively. The dielectric measurements were made both as function of frequency and temperature. (c) 2007 Elsevier B.V. All rights reserved.
