PinPoint™ Conductive AFM

PinPoint™ Conductive AFM obtains the best of resolution and sensitivity during current measurements

PinPoint™ Conductive AFM was developed for well defined electric contact between the tip and the sample. They XY scanner stops while measuring the electric current with contact time controlled by a user. PinPoint™ Conductive AFM allows higher spatial resolution, without lateral force, with optimized current measurement over different sample surface.

1. The XY scanner stops during acquisition
2. Approach and retract at each pixel point.
3. Record the approach height and maintain the Z distance.

The conventional contact and tapping conductive AFM have cons and pros.
PinPoint iAFM has the best of both spatial resolution and current sensitivity.
