在这份简报中，我们观察到10 keV的O-离子（50 pA/mm（2））通过Al 2 O3纳米胶囊传输的动态引导。透过的氧离子逐渐向毛细管轴方向移动，角半高宽也显著增大。而O-离子的透过率降低。这些数据意味着沉积在毛细管中的电荷对入射的O-离子提供了足够的引导力。
In this Brief Report, we observed the dynamic guiding of 10-keV O- ions (50 pA/mm(2)) transmitting through Al2O3 nanocapillaries. The transmitted O- ions shift gradually to the direction of the capillary axis, and the angular FWHM also increases significantly. However, the transmission rate of O- ions decreases. The data imply that the charges deposited in capillaries provide a sufficient guiding force to the incident O- ions.
