Atomic force microscopy/Inventors

History. The AFM was invented by IBM scientists in 1985. The precursor to the AFM, the scanning tunneling microscope (STM), was developed by Gerd Binnig and Heinrich Rohrer in the early 1980s at IBM Research – Zurich, a development that earned them the 1986 Nobel Prize for Physics.

What is the use of atomic force microscopy?

Atomic-force microscopy (AFM) is a powerful technique that can image almost any type of surface, including polymers, ceramics, composites, glass, and biological samples. AFM is used to measure and localize many forces, including adhesion strength, magnetic forces, and mechanical properties.

What is cantilever In AFM?

An AFM uses a cantilever with a very sharp tip to scan over a sample surface. As the tip approaches the surface, the close-range, attractive force between the surface and the tip cause the cantilever to deflect towards the surface.

Can you see an atom with a microscope?

Atoms are really small. So small, in fact, that it’s impossible to see one with the naked eye, even with the most powerful of microscopes. Now, a photograph shows a single atom floating in an electric field, and it’s large enough to see without any kind of microscope.

Is atomic force microscopy destructive?

Since then it has developed into a powerful measurement tool for surface analysis. AFM allows accurate and non-destructive measurements of the topographical, electrical, magnetic, chemical, optical, mechanical, etc. properties of a sample surface with very high resolution [2] in air, liquids or ultrahigh vacuum.

What is atomic force microscopy in nanotechnology?

Atomic-force microscopy (AFM) is a surface scanning technique that has sub-nanometer scale resolution. AFM describes a group of techniques used for non-destructive surface studies at the nanoscale. They have a resolution on the order of 103 times better than optical microscopy’s resolution limit.

What does TEM stand for?

Transmission electron microscopy (TEM) is a microscopy technique in which a beam of electrons is transmitted through a specimen to form an image.
