AFM tip with carbon nanotube extension . AFM vs STM. AFM refers to Atomic Force Microscope and STM refers to Scanning Tunneling Microscope. The development of these two microscopes is Nov 8, 2014 A Scanning probe techniques. Spectroelectrochemistry (ch. 16/17).
Atomic Force Microscopy and Scanning Tunneling Microscopy Atomic Force Microscope (AFM) STM makes use of tunneling currentIt can only image conducting or semiconducting surfaces. Binnig, Quate, and Gerber invented the Atomic Force Microscope in 1985. It can image almost any type of surface, including polymers, ceramics, composites, glass, and biological samples.

The AFM has the advantage of imaging almost any type of surface, including polymers, ceramics, composites, glass, and biological samples.
1. AFM captures precise images by moving a nanometer sized tip across the surface of the image.

ATOMIC FORCE MICROSCOPY (AFM) Presented by, Raihanathus Sahdhiyya A I M.Sc. Microbiology 2. HISTORY OF AFM In 1981, G.Binning and H.Rohrer invented Scanning Tunneling Microscope and was awarded Nobel for this in 1986 The modified version of this, which is in use now was invented in 1989 called “Atomic Force Microscopy” 3. 2017-04-23 Scanning Probe Microscopes (SPMs) Monitor the interactions between a probe and a sample surface What we “see” is really an image Two types of microscopy we will look at: Scanning Tunneling Microscope (STM) Atomic Force Microscope (AFM) Scanning Tunneling Microscopes (STMs) Monitors the electron tunneling current between a probe and a sample 2010-10-24 Atomic force microscopy (AFM) sometimes referred to as scanning force microscopy (SFM) is a microscopy technique used to give a topographical image of a surface i.e. allows the analysis of the shape and features of the surface. It has relatively good resolution, though not as good as scanning tunnelling microscopy (STM).
