The AFM principle is based on the cantilever/tip assembly that interacts with the sample; this assembly is also commonly referred to as the probe. The AFM probe interacts with the substrate through a raster scanning motion. The up/down and side to side motion of the AFM tip as it scans along the surface is monitored through a laser beam reflected off the cantilever.

Atomic force microscopy diagram

In this article we will discuss about the design of atomic force microscope, explained with the help of a diagram. An atomic force microscope instead of using a lens is provided with a probe to examine the surface of a specimen with a sharp tip which may be several micrometers in and less than 10 nm in diameter at the point near field to be examined. The tip lies at the end of the lever which ... Scanning probe microscopy has been the engine of characterization in nanoscale systems ().Atomic force microscopy (AFM) in particular has developed into a leading technique for high-resolution studies without material restrictions (3-5).It is increasingly being used for detailed characterization in a wide variety of physical, biological, and chemical processes (6, 7). Functionalizing the tip of an atomic force microscope with a CO molecule enabled atomic-resolution imaging of single molecules, and measurement of their adsorption geometry and bond-order relations. In addition, by using scanning tunneling microscopy and Kelvin probe force microscopy, the density of the molecular frontier orbitals and the ...

Atomic force microscopy diagram. 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). 2.1. Atomic Force Microscopy (AFM) AFM is a topographic imaging technique with high spatial resolution (a lateral resolution of 1 nm and a vertical resolution of 0.1 nm), and can be used to acquire mechanical properties [].The principle of AFM (Figure 1) is that the sample can be imaged at atomic resolution by detecting the near-field interactions between a tiny tip and the sample surface [17,18].

Atomic force microscopy (AFM) is a kind of scanning probe microscopy, where a probe or tip is used to map the contours of the sample. During operational mode, the tip connected to a cantilever is scanned over the surface of the sample, with a small repulsive force present between the sample and the tip.

Atomic force microscopy (AFM) is a 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.The information is gathered by "feeling" or "touching" the surface with a mechanical probe.

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).
