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. Gerd Binnig (1947) Calvin Quate (1923) STM / AFM Images - Scanning Tunneling Microscopy In 1981, the Scanning Tunneling microscope was developed by Gerd Binnig and Heinrich Rohrer IBM Zurich Research Laboratories in | PowerPoint PPT presentation | free to view 2013-11-05 Brief History of 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, 2014-04-06 Basic components of STM: Five basic components: 1.

The are two types of SPMs – Scanning Tunneling Microscope (STM) and Atomic Force Microscope (AFM). The STM was invented Background of AFM In 1929 Shmalz described Stylus Profiler.

In AFM, the tip touches the surface; meanwhile, in STM, there is a short distance between the tip and the surface.
