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

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.
