利用热激电流（TSC）和空间电荷分布的同时测量结果，计算了不同温度下电子束辐照PMMA中电子的迁移率。在前一篇文章中，通过同时测量TSC和空间电荷分布，得到了真实的传导电流。为了同时精确测量TSC和空间电荷分布，采用脉冲电子声（PEA）方法开发了一种新的计算机控制系统。本文利用新系统得到的传导电流结果，估计了电子束辐照PMMA的迁移率。从这些结果可以看出，电子迁移率随温度的升高而增加。
The mobility of electrons in electron beam (e-beam) irradiated PMMA at various temperature was calculated from simultaneous measurement results of thermally stimulated current (TSC) and space charge distribution. In former paper, it is shown that the real conduction current is obtained by the simultaneous measurement of TSC and space charge distribution. To measure the precise TSC and space charge distribution simultaneously, a new computer control system has been developed using pulsed electron acoustic (PEA) method. In this paper, the mobility in e-beam irradiated PMMA is estimated from the results of the conduction current which is obtained using the new system. From these results, it is found that the electron mobility increases with increasing temperature.
