摘要：

Pure KH2PO4 (KDP) and KDP crystals containing KBr and NaBr with/without gold doping were grown by slow evaporation technique. All the grown crystals were gamma- irradiated using Co-60 source. Electrical conductivity measurements were carried out perpendicular to the unique direction before and after gamma-irradiation. The present measurement shows that the conductivity of KDP crystals increases with the addition of KBr and NaBr and with gold-doping as well as temperature. Computed values of activation energies from the conductivity measurements are given. Dielectric constant is measured as a function of frequency. Study confirms the contribution of space charge polarization.
