- Description
- The scan rate of tapping mode Atomic Force Microscopy (AFM), when scanning in air, may be improved by reducing the quality (Q) factor of the micro-cantilever. Passive piezoelectric shunt control is implemented in the AFM by placing an electrical impedance in series with the cantilever tip oscillation circuit. This method is used to reduce the Q factor of a piezoelectric self actuating AFM micro-cantilever by a factor of 8. Experimental results demonstrate that scan rate and image quality may be improved significantly using this method.
