Study of Dielectric Constant of Glycine Doped Ammonium Dihydrogen Phosphate (ADP) Crystal

Abstract

To enhance the properties of Ammonium dihydrogen phosphate (ADP) crystals, it has been doped with simplest amino acid, Glycine. ADP with Glycine dopant and Ammonium dihydrogen phosphate (ADP) crystals have been grown by slow conventional, rotation and SR methods and subjected to dielectric characteristics. The dielectric constant has been measured which increases with rise in temperature for pure ADP crystals and conventional, rotation and SR method grown Glycine doped ADP crystals. It is beingnoted that doped crystals have higher dielectric constant than pure ADP crystal and found to agree with the reported values. SR method grown crystals were found to possess highest dielectric constant among all the grown crystals. Higher dielectric constant directs that the grown crystalspossess good crystalline quality with lesser defects.
