Abstract

Experiments were carried out to study the transmission of \(3\hbox {-keV Ne}^{7+}\) ions through nanocapillaries in polyethylene terephthalate (PET). The capillaries were highly parallel with a diameter of 230 nm and a length of \(12\, \mu \hbox {m}\). The transmission during the charging and discharging processes was measured for different tilt angles ranging from \(3^{\circ }\) to \(9^{\circ }\). An advanced instrumental technique was employed to avoid recharging effects during the discharging process. During discharging, the decay of the guided transmission is found to be non-exponential depending strongly on the tilt angle. The experiments were interpreted by model calculations using a minimum number of free parameters. The discharging results for different tilt angles are reproduced by a single decay function involving nonlinear properties. After measuring the discharge for nearly 7 hours, the charge depletion rate was found to be unexpectedly small resulting in a long duration of the charges in the capillary.

摘要

进行实验以研究\（3 \ hbox {-keV Ne} ^ {7 +} \）离子在聚对苯二甲酸乙二醇酯（PET）中通过纳米毛细管的传输。毛细管高度平行，直径为230 nm，长度为\（12 \，\ mu \ hbox {m} \）。针对在从\（3 ^ {\ circ} \）到\（9 ^ {\ circ} \）范围内的不同倾斜角，测量了充电和放电过程中的透射率。为了避免在放电过程中产生再充电效应，采用了一种先进的仪器技术。在放电期间，发现导向传动装置的衰减是非指数的，很大程度上取决于倾角。通过使用最少数量的自由参数进行模型计算来解释实验。通过涉及非线性特性的单个衰减函数可以再现不同倾斜角的放电结果。在测量放电近7小时后，发现电荷耗竭率出乎意料地小，导致毛细管中电荷的持续时间长。
