Abstract
The electric scanning force microscope (EFM) is used for the high-reso lution characterization of electrically polar substances. An EFM is co nsidered, the tip of which is electrically conductive and has a given potential. The tip of the EFM is exposed to Maxwell stress caused by f erroelectric domains and sample permittivity. This Maxwell stress is a nalytically calculated in a one-dimensional model. The results of calc ulation are compared with the results of EFM measurements. The method for measuring ferroelectric domains is in particular discussed.
