Atomic Force/Scanning Probe Microscopy: Atomic force microscopy (AFM), scanning force microscopy (SFM) is a high-resolution microscopic technique where the microscopic information is gathered by "feeling" the surface with a mechanical probe. Piezoelectric scanners facilitate (in x,y and z directions) tiny, but accurate, movements to enable very precise scanning. With demonstrated resolution on the order of fractions of a nanometer, more than 1000 times better than the optical diffraction limit, AFM has become a standard technique for surface analysis of materials. The precursor to the AFM, the scanning tunneling microscope, was developed by Gerd Binnig and Heinrich Rohrer in the early 1980s at IBM Research - Zurich, a development that earned them the Nobel Prize for Physics in 1986. Binnig, Quate and Gerber invented the first atomic force microscope in 1986. The first commercially available atomic force microscope was introduced in 1989.
