In order to study avalanche ionization mechanism, it is inevitable to deal with rates of electrons absorbing and losing energy.

研究雪崩破坏机理,必然涉及到电子吸收激光能量的速率和电子损耗能量的速率,这些都与电子和声子的散射有密切的联系。

N-channel MOS transistors from CC4007,CC4011 and LC54HC04RH device were irradiated with different dose rate Co-60 gamma rays,lower energy protons(less then 9MeV)and 1MeV electrons.

利用不同剂量率γ射线、低能 (小于 9MeV)质子和 1MeV电子对CC40 0 7RH、CC40 11、LC5 4HC0 4RHNMOS FET进行了辐照实验 ,结果表明 ,在 +5V偏置条件下 ,9MeV以下质子造成的损伤总是小于60 Co,而且质子能量越低 ,损伤越小 ;对于同等的吸收剂量 ,1MeV电子和60 Co造成的损伤差别不大 ;在高剂量率γ射线辐射下 ,氧化物陷阱电荷是导致器件失效的主要原因 ,在接近空间低剂量率辐射环境下 ,LC5 4HC0 4RH电路失效的主要原因是辐射感生界面态陷阱电荷 ,而CC40 0 7RH器件则是氧化物陷阱电荷 。
