摘要

研究了γ辐照对量子电子器件中广泛使用的磷酸二氢钾KH2PO4 (KDP)单晶直流电导率的影响。体积电导率的测量在20-100℃温度区间内实现。随着辐照剂量的增加，KDP样品的电导率基本降低。测量了晶体直流电导率的温度依赖性，并计算了电导率活化能的数值。从所获得的数据可以看出，在辐照过程中，电导率参数发生了明显的变化。观察到辐照后的活化能增加

Investigation of Electrical Conductivity of KH2PO4 Single Crystals

The effect of gamma-irradiation on electrical dc conductivity of potassium dihydrogen phosphate KH2PO4 (KDP) single crystals widely used in quantum electronics devices is investigated. The measurements of bulk conductivity were realized within 20-100 degC temperature interval. The conductivity in the samples of KDP was found to essentially decrease with an increase of gamma-irradiation dose. The temperature dependences of dc conductivity in the crystals were measured, and numerical values of the activation energy for conductivity were calculated. As follows from the data obtained, in the process of gamma-irradiation noticeable changes of the conductivity parameters take place. It is observed that the activation energy increases after gamma-irradiation
