HI-RES probe has a hydrophobic diamond-like
extratip at the apex of silicon etched probe. In general, there are additional
smaller extratips near the main one.
Typical probe tip radius
1 nm
Height of extratip
100
.. 200 nm
Total probe tip height
20..25 µm
Maximum allowed height of surface feature for scanning
< 20nm*
*Though the extratips are of different height and angle,
they can contribute to imaging of rough surfaces, which result in repeating
of the features in the scan.
