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

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.
