Thermal, dielectric, and surface analysis of NaDP doped glycine phosphite single crystals

Abstract

Transparent, unidirectional single crystals of sodium dihydrogen phosphate-doped glycine phosphite (NaDP–GPI) are grown by the Sankaranarayanan-Ramasamy method. The good quality crystal is obtained under controlled thermal conditions. The functional groups and melting temperature of NaDP–GPI single crystals are analysed. The phase transition temperature of NaDP–GPI is calculated from the dielectric studies. The mound-like patterns are observed on the surface of the crystal. The growth process under the controlled thermal condition was observed by optical studies. The obtained results are discussed in detail.
