论文摘要
在这项工作中,重新审视原子力显微镜中的尖端卷积效应,以说明立方对象确定尖端形状和尺寸的能力。使用基于分子的立方纳米颗粒作为参考,已经开发了两步尖端重建过程。首先,通过对卷积误差的分析,在从实验曲线中提取尖端半径时,通过分析卷积误差来估计尖端到面角。获得的结果与小费供应商的规范非常吻合,即使使用纳米颗粒的实际分布进行了大小和纵横比的分布进行实验。这证明了我们方法的可靠性,并通过使用纳米光刻模式为更准确的尖端重建打开了大门。
In this work, the tip convolution effect in atomic force microscopy is revisited to illustrate the capabilities of cubic objects for determination of the tip shape and size. Using molecular-based cubic nanoparticles as a reference, a two-step tip reconstruction process has been developed. First, the tip-to-face angle is estimated by means of an analysis of the convolution error while the tip radius is extracted from the experimental profiles. The results obtained are in good agreement with specification of the tip supplier even though the experiments have been conducted using real distribution of nanoparticles with dispersion in size and aspect ratio. This demonstrates the reliability of our method and opens the door for a more accurate tip reconstruction by using nano-lithography patterns.
