Physics
Atomic force microscope
A flexible cantilever traces a nanoscale surface and builds an image.
Try this
The tip scans a smooth nanoscale terrace and a rounded bump. Compare true topography with the feedback reconstruction: excessive scan speed makes the probe lag behind the surface.
The model and its limits
Spherical-tip geometric dilation plus Hertz contact and an elastic cantilever. Prescribed sample, no adhesion or tapping-mode dynamics. Scales are enlarged.
Equations used in the module
Equations F = k d F = (4/3) E* √R δ^(3/2)
