PDF Lecture 10: Basics of Atomic Force Microscope (AFM) Atomic force microscopy (AFM) was developed when people tried to extend STM technique to investigate the electrically non-conductive materials, like proteins. In 1986, Binnig and Quate demonstrated for the first time the ideas of AFM, which used an ultra-small probe tip at the end of a cantilever (Phys. Rev. Letters, 1986, Vol. 56, p 930). Atomic Force Microscope Principle | AFM Scanning | How AFM ... Atomic force microscopy is arguably the most versatile and powerful microscopy technology for studying samples at nanoscale. It is versatile because an atomic force microscope can not only image in three-dimensional topography, but it also provides various types of surface measurements to the needs of scientists and engineers.

Atomic Force Microscope - an overview | ScienceDirect Topics The deflections that occur in the tip, due to the interaction forces between the tip and sample surface, can be measured by focusing a laser beam onto a cantilever and detecting the reflected light from the cantilever using a position sensitive detector. Schematic diagram showing the principle of atomic force imaging is shown in Fig. 4.1a. As the tip is moved over the surface, a feedback mechanism is employed to ensure that the piezoelectric motor maintains a constant tip force or height ...

Atomic Force Microscope (AFM)- Definition, Principle ... The Atomic Force Microscope (AFM) takes the image of the surface topography of the sample by force by scanning the cantilever over a section of interest. Depending on how raised or how low the surface of the sample is, it determines the deflection of the beam, which is monitored by the Positive-sensitive photo-diode (PSDP).
