Big Hole¶
Symptoms¶
The NanoFrazor writes a big hole instead of the target pattern even though the depth feedback has already set the force to the minimum (0 V).
Cause¶
The hot tip is touching the surface even when no electrostatic force is applied. For further details consult the section on the Forward (writing) Height.
Solution¶
Increase the write height to separate the tip and sample when the heater is on. If the write height is already larger than 400 nm, decrease the writer temperature/voltage.
