Summary
[edit]DescriptionAtomic Force Microscopy (AFM) tip attached to a tuning fork.jpg |
English: This picture shows the tip assembly of an Atomic Force Microscope (AFM). A very fine tip is attached to one of the legs of a quartz tuning fork (bottom leg in the picture). The quartz tuning fork oscillates with its natural frequency. As the tip scans over a surface at a close range (distance between tip and surface ~ few nanometers), the natural frequency of oscillation of the tuning fork changes due to interaction of tip with atoms/molecules on the surface. By measuring these shift in the natural frequency of tuning fork oscillations as the tip scans over a surface, a topographic map of the surface with nanometer size resolutions can be made.
This picture of AFM tip assembly was taken using a phone camera attached to a stereo microscope. |
