摘要/Abstract

摘要： 实验观察到双轴拉伸聚2,6-萘二甲酸乙二醇酯(PEN)的γ-辐射诱导我流子品种转变现象,检测到发生转变的剂量范围,在γ-辐射诱导陷阱变浅的实验基础上讨论了载流子品种转变的实质,研究了非晶及双拉PEN热驻极体在γ-辐射激励下电荷储存、迁移机理及解驻极效应。

关键词: 驻极体, 载流子品种, 局域能级, 陷阱深度, 辐射诱导

Abstract: The detrapping currents from poly(2,6-ethylene naphthalene dicarboxylate) (PEN) films r-irradiated at doses ranged over 5× 10⁴ Gy were determined by means of Thermally Stimulated Current (TSC) technique, and the various electrode materials were used.The sign transition of main species of charge carriers in biaxial stretched PENfilm was observed.It is explained that this transition results from shifting of sub-Fermi levels of electrons and holes since the r-irra-diation causes decreasing of mean trap levels.The de-electreting phenomena of both amorphous and biaxial stretched PENelectrets have been investigated.The mechanism of moving of charge carriers during de-electreting process is discussed.

Key words: Electret, Specise of charge carriers, Localized energy level, Trap depth, Irradiation inducing
