Atomic Force Microscope: Principle, Parts, Uses - Microbe Notes
2023年6月5日 · The atomic force microscope (AFM) is a type of scanning probe microscope whose primary roles include measuring properties such as magnetism, height, friction. The resolution is measured in a nanometer, which is much more accurate and effective than the optical diffraction limit.
Atomic force microscopy - Wikipedia
Atomic force microscopy (AFM) or scanning force microscopy (SFM) is a very-high-resolution type of scanning probe microscopy (SPM), with demonstrated resolution on the order of fractions of a nanometer, more than 1000 times better than the optical diffraction limit.
Atomic Force Microscope (AFM) – Definition, Principle, …
2024年4月13日 · Atomic force microscopy (AFM) is a form of scanning probe microscopy (SPM) with a resolution so high that it can detect molecules within a fraction of a nanometer. A mechanical probe is used to collect information by touch with the assistance of piezoelectric devices that enable very small yet precise motions via electrical control for ...
AFM Principle - How Does an Atomic Force Microscope Work?
AFM microscopes operate on the principle of surface sensing using an extremely sharp tip on a micromachined silicon probe. This tip is used to image a sample by raster scanning across the surface line by line, although the method varies dramatically between distinct operating modes.
AFM, which uses a sharp tip to probe the surface features by raster scanning, can image the surface topography with extremely high magnifications, up to 1,000,000X, comparable or even better than electronic microscopes. The measurement of an AFM is made in three dimensions, the horizontal X-Y plane and the vertical Z dimension.
