Atomic Force Microscopy (AFM) Atomic Force Microscopy (AFM)The main principle of AFM is to cause a micro displacement of the cantilever (which carries the probe) using the atomic forces between the probe tip and the sample, to map the topography of the sample. AFM is applicable to various ...
Atomic Force Microscopy (AFM) traces the topography of samples with extremely high - up to atomic - resolution by recording the interaction forces between the surface and a sharp tip mounted on a cantilever. In addition to topographic high-resolution inf
1. How does Atomic Force Microscopy Work? In an atomic force microscope(AFM) a sharp probe is mechanically scanned across a surface and the motion of the probe is captured with a computer. The probe's motion is then used to create a three dimensional image of the surface. In the AFM ei...
原子力显微镜 Atomic Force Microscopy (AFM) 原子力显微镜(AFM)是扫描探针显微镜(SPM)的一种方法,它是一种测量局部性质(如高度、摩擦力和磁性)的综合技术。AFM由悬臂末端的尖端作为探针组成,探针通常为3-6µm高的棱锥体,端部半径为15-40nm,用于测量探针与样品表面之间的作用力。 原子力显微镜利用光学杠杆测量...
AFM 力谱是指单点测量,其中悬臂接近并“刺入”样品,然后缩回。在此过程中,测量悬臂偏转与压电运动,最终将其转换为力与尖端-样品分离的测量,从而提供有关样品的机械信息。这种转换需要校准弹簧常数和偏转灵敏度。 悬臂偏转与Z压电的模型力曲线如下: 力曲线可分为不同的部分,其中A-C(黑线)是指尖端接近表面时的运...
