不同剂量率下偏置对双极晶体管电离辐照效应的影响

对双极晶体管进行了不同剂量率、不同偏置的电离辐照实验。结果表明，对于不同偏置条件，晶体管在低剂量率辐照下，电流增益都有更为明显的衰降；各种剂量率辐照下，电流增益在发射结反向偏置时比浮空偏置时有更为显著的下降。文章对相关机理进行了探讨。

Effects of Bias at Different Dose Rates on Ionizing Radiation Response of Bipolar Transistors

Ionizing radiation response of bipolar transistors at different dose rates and biases has been investigated. It has been shown that the current gain deteriorates significantly at low dose-rate for transistors at different bias conditions, and the degradation becomes more significant at emitter reverse bias than at floating bias when irradiated at different dose-rates. Possible mechanisms for these effects have also been discussed.
