光激活电荷畴(PACD)在半绝缘GaAs和GaAs光导开关的非线性模式中起着重要作用。本文讨论了光激活电荷畴的形成和输运过程,指出是屏蔽电场导致了PACD的独特分布和演化规律。PACD通过其屏蔽效应限制光电导体中的空间电荷电流和光电导开关的输出电流。
The photoactivated charge domain (PACD) plays an important role in the nonlinear modes of semi-insulating GaAs and LnP photoconductive switches. The formation and transporting process of photoactivated charge domain are discussed in this paper, which indicate that it is the shielded electric field that induced the unique distribution and evolution law of the PACD. The PACD restricts space-charge current in the photoconductor and the output current of the photoconductive switch by its shielded effect.
