4 PREPARATION FOR OBSERVATION
CAUTION
1. Be sure to insert the cantilever along with the groove.
Otherwise, the cantilever may be damaged due to an excessive
force being applied when the spring retainer is released.
2. Never touch the area around the cantilever on the cantilever
holder with bare fingers. If that part is contaminated with hand
grease, that might give rise to insufficient insulation, thus
possibly causing tunneling current leakage or incorrect
operation of the piezoelectric element.
3. Push the spring retainer vertically. If you force it diagonally, the
ceramic might be damaged.
3.
Release the spring retainer slowly to lock the cantilever in place.
4.1.6 Mounting the Tip
Below is the procedure for mounting the tip on the tip holder in order to perform STM
observation.
To mount the tip on the tip holder, insert the tip into the plunger while pushing the
plunger as shown in the figure below to align the external and internal tip-mounting
holes. Make sure that the length from the top of the tip to the surface of the tip mounting
base is 2 mm.
