Atomic Force Microscopy (AFM)
  

Working Principles

  

Atomic force microscopy is  the most versatile and powerful microscopy technology for studying samples at nanoscale. It is versatile because an atomic force microscope can not only image in three-dimensional topography, but it also provides various types of surface measurements. It is powerful because an AFM can generate images at atomic resolution with angstrom scale resolution height information, with minimum sample preparation.

To obtain an image, a cantilever is scanned over the sample surface. A laser beam is deflected off the back of the cantilever, and changes in deflection are monitored with a photodiode detector.
