热电流是从电晕充电聚酯薄膜中获得的。结果根据电子和/或离子捕获以及随后在重新加热时的释放来解释。开发了一种理论，用于在不施加外部场时这些“近表面”带电样本的热释放。提出了一种新方法来获取复杂热电流谱中存在的一系列峰的能量。还使用 Garlick 和 Gibson 的初始上升分析以及 Cowell 和 Woods 的曲线拟合技术来确定捕获参数。结果与聚酯薄膜中深度为 0.55、0.85、1.4 和 2.2（均为 ±0.1）eV 的四个离散陷阱一致。 0.55 eV 和 0.85 eV 陷阱是电子陷阱，1.4 eV 要么是带有库仑势垒的电子陷阱，要么是离子陷阱。 2.2-eV 陷阱要么是离子的、界面的，要么涉及复合物的解离，随后将电子释放到导带。假设陷阱在单分子条件下为空，分析...
Thermal currents have been obtained from corona‐charged Mylar. The results are interpreted in terms of electron and/or ion trapping and subsequent release upon reheating. A theory is developed for thermal release of these ``near surface'' charged specimens when no external field is applied. A new method is presented to obtain energies for a series of peaks present in complex thermal current spectra. The trapping parameters are also determined using both the initial rise analysis of Garlick and Gibson, and the curve fitting technique of Cowell and Woods. The results are consistent with four discrete traps in Mylar at depths of 0.55, 0.85, 1.4 and 2.2 (all ±0.1) eV. The 0.55‐ and 0.85‐eV traps are electronic, that at 1.4 eV is either an electronic trap with a Coulomb barrier, or ionic. The 2.2‐eV trap is either ionic, interfacial, or involves dissociation of a complex with subsequent release of an electron to the conduction band. Assuming that the traps empty under monomolecular conditions, analysis of the ...
