【 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 ð›�? -irradiated using ⁶⁰Co source. Electrical conductivity measurements were carried out on all these crystals perpendicular to the unique direction before and after ð›�?-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.
