利用针尖-表面相互作用动态标定原子力显微镜中悬臂梁的高阶本征模参数

Dynamic Calibration of Higher Eigenmode Parameters of a Cantilever in Atomic Force Microscopy Using Tip-Surface Interactions

Stanislav S. Borysov, Daniel Forchheimer, David B. Haviland

摘要:

我们提出了一个理论框架的悬臂梁的高本征模参数(刚度和光杠杆响应)的动态校准。该方法是基于尖端表面力重建技术,不需要任何先验知识的本征模式的形状或特定形式的尖端表面相互作用。所提出的校准方法需要使用多模态驱动器的单点力测量,并且其精度与较高本征模的未知物理振幅无关。

英文摘要:

We present a theoretical framework for the dynamic calibration of the higher eigenmode parameters (stiffness and optical lever responsivity) of a cantilever. The method is based on the tip-surface force reconstruction technique and does not require any prior knowledge of the eigenmode shape or the particular form of the tip-surface interaction. The calibration method proposed requires a single-point force measurement using a multimodal drive and its accuracy is independent of the unknown physical amplitude of a higher eigenmode.
