Structural and Dielectric Investigations on Pure and Doped Triglycine Sulfate (TGS) Crystals

Abstract

Abstract: In this paper, a single crystal triglycine sulfate (TGS) doped with copper sulfate was synthesized using the slow evaporation technique. Structural characterization was carried out using X-ray diffraction and FTIR techniques. Thermal studies revealed that the addition of copper sulfate did not affect the thermal stability of the TGS. In addition, intensive dielectric investigation has been carried out, which showed that the addition of copper sulfate enhances the dielectric permittivity. A change in Curie temperature has been observed upon doping TGS with copper sulfate. Keywords: TGS doping, Copper sulfate, Dielectrics, Cole-Cole plot.
