Chapter V Dielectric Study of …… - The conduction in KDP occurs through protons and mainly due to anions; the additional hydrogen bonds created may reduce the L-defects and as a result obstruct the movement of protons. This corresponds to the observation of Meena and Mahadevan [42] that the a.c. resistivity values increases on increasing amino acid doping concentration. The addition of amino acid decreases tan and dielectric constant values of KDP crystals in comparison to pure KDP crystals, this also corresponds to the earlier reported observation [42]. The significant lowering of dielectric constant on increasing the amino acid can make the doped KDP crystals good candidates for electro- optic applications. 217
Chapter V Dielectric Study of …… - Conclusion 1. The dielectric constant of pure and amino acids doped KDP crystals decreased as the frequency of applied field increased and ultimately became constant at high frequency. This might be due to the dipoles could not comply with the rapid changes in the alternating electric field. 2. At any range of frequency the dielectric constant of the doped KDP crystals was found to be lower than those for pure KDP crystals, which might be due to generation of L-defects on addition of amino acids. 3. As the doping of amino acids increased the dielectric loss of KDP crystals decreased. The nature of the variation of dielectric loss with frequency was similar to that of the dielectric constant with frequency. The low values of dielectric loss in doped crystals indicated that the doping of amino acids did not bring major defects. 4. The variation of a.c. resistivity with frequency of applied field suggested that the resistivity decreased with increasing the frequency and its value increased on increasing the amount of amino acids doping. 218
