Ion transport in Au~+ doped/undoped KDP crystals with KI/NaI as additives

摘要

Undoped KDP and KDP crystals containing KI/NaI with/without gold doping were grown by slow evaporation technique. All the grown crystals were gamma-irradiated using ~(60)Co source. Electrical conductivity measurements were carried out on all these crystals perpendicular to the unique direction before and after gamma-irradiation. The present results show that the conductivity of KDP crystals increases with the addition of KI/NaI and with gold doping as well as upon rise in temperature. Computed values of activation energies from the conductivity measurements are given. For all the grown crystals, dielectric constant is measured as a function of frequency.
