Electrostatic Force Microscopy
EFM is based on the dual pass scheme. The grounded tip first acquires the surface topography using standard intermittent contact atomic force microscopy (IC-AFM). Electrostatic data are collected above the surface. In EFM, the cantilever is driven mechanically and the electro-static force F between the dc biased conductive tip and the surface results in a change of the cantilever resonant frequency that is proportional to the force gradient

Dw=(wo/2k) (dF(z)/dz)

where k is the spring constant and wo is the resonant frequency of the cantilever. Resonance is maintained by adjusting the driving frequency wp and the frequency shift Dw= wp- wo is collected as the EFM image.

An a.c.voltage, U,
U=Uwsin(w t)
of radian frequency, w, is present between the electrically conductive tip of the microscope and the electrode at the back of the sample. Both electrostatic forces (so-colled "Maxwell stress ") and electromechanically induced forces act on the tip. An oscillating electric field causes thickness vibrations of the sample due to electrome-chanical effects (inverse piezoelectric effect and electrostriction).
