Atomic force microscopy definition of Atomic force microscopy in the Free Online Encyclopedia.

atomic force microscope (AFM), device that uses a spring-mounted probe to image individual atoms on the surface of a material. Unlike the scanning tunneling microscope scanning tunneling microscope, device for studying and imaging individual atoms on the surfaces of materials. The instrument was invented in the early 1980s by Gerd Binnig and Heinrich Rohrer, who were awarded the 1986 Nobel prize in physics for their work.

In the original AFM, the probe traverses the surface, moving upward due to bumps and downward due to depressions; a laser laser [acronym for light amplification by stimulated emission of radiation], device for the creation, amplification, and transmission of a narrow, intense beam of coherent light.

Another type of AFM measures the sideways deflection of the tip caused by friction as the probe moves across the surface; differences in friction can be used distinguish different atoms and molecules on the material. A third variation employs a magnetic probe; this probe does not touch the material but moves up and down in reaction to the magnetic forces between the tip and the surface. In a microchip-size AFM, the electronic circuitry and multiple probes are integrated on a sliver of silicon; although less sensitive than a full-size AFM, the device has applications in microelectronics microelectronics, branch of electronic technology devoted to the design and development of extremely small electronic devices that consume very little electric power.

(engineering)

A device for mapping surface atomic structure by measuring the force acting on the tip of a sharply pointed wire or other object that is moved over the surface.
