Hence, the AFM functions by just measuring the little force between the tip and surface. AFM is more accepted in nanotechnology simply because it has been discovered to have a … 2018-07-04 2011-07-02 The scanning tunneling microscope (STM) and atomic force microscope (AFM) provide, not only ‘eyes’ but also ‘hands’ to investigate and modify nano-objects.
