Using Quartz Crystal Resonators as Shear Force Transducers for SECM

2 Using Quartz Crystal Resonators as Shear Force Transducers for SECM 

The tip was first brought into very close proximity to the surface by shear force feedback the approach was stopped when a 3%-5% damping of the fork oscillation was recorded. The tip was then withdrawn by 24nm, before the ECL light intensity transmitted to the substrate was monitored. This tapping mode-like procedure was repeated for every imaging position of the substrate. The 

Using quartz crystal resonators as shear force transducers for distance control in SECM is seemingly universal, since it simply requires the gluing of a low mass probe to a crystal resonator to
