金硅面垒型半导体探测器在氢气环境下失效现象的实验研究

Research of Failure of Au-Si Surface Barrier Semiconductor Detector in Hydrogen Condition

当金硅面垒型半导体探测器在氢气环境下使用的时候,α能峰会向低能方向飘移,直至淹没在电子学噪声中。本文通过实验介绍了金硅面垒探测器在氢气环境下的这种失效现象,总结了失效现象的规律;提出了金硅面垒探测器在氢气环境受影响的机理,并进行了实验验证。

While Au-Si surface barrier semiconductor detector is used in hydrogen condition,alpha peak moves slowly toward the direction of low energy until it immersed electronics noise.The failure phenomenon of Au-Si surface barrier detector in hydrogen condition is introduced,and the rule of this phenomenon is summarized.On the basis of these,the reason of the hydrogen condition impact on Au-Si surface barrier detector is presented.
