WebTopography. The most common mode of STM measurement employed by STM groups around the world is a topography. In this mode, we raster the tip across the surface at a fixed sample bias voltage V set, and employ a feedback loop which controls the voltage on the z piezo to keep the tunneling current constant at I set. WebForces between the tip and sample cause changes to the oscillation . A feedback loop maintains constant oscillation amplitude by adjusting tip height with a voltage applied to a piezo element . Applied voltage relates to topography with minimal damage to surface and tip. Tapping mode AFM is the common mode for topography imaging.
