摘要

在本报告中,我们展示了一种超声波纳米线切割方法,该方法利用微型工具尖端的线性振动和水分子在NW和衬底之间的固定能力。在96.9 kHz频率下,以18 ~ 220 mm/s的振动速度切割直径为50 ~ 400 nm的纳米线。实验明确了最小切削速度和最佳切削速度范围下限与NW直径的关系。比较了微切削刀具椭圆振动对切口质量的影响。

Ultrasonic cutting of individual silver nanowires by a linearly vibrating micro tool
In this report, we demonstrate an ultrasonic nanowire cutting method, which uses the linear vibration of the tip of a micro tool and the fixing capability of the water molecules between the NW and substrate. The nanowires with a diameter from 50 nm to 400 nm are cut by the needle with the vibration velocity amplitude from 18-220 mm/s at 96.9 kHz. The dependency of the minimum cutting velocity and lower limit of the optimum cutting velocity range on the NW diameter is experimentally clarified. The incision quality is compared with that caused by an elliptical vibration of the micro cutting tool.
