Abstract
A theoretical method for the imaging of metallic objects in electrostatic force microscopy is presented. The technique, based on the generalized image charge method, includes intrinsically the mutual polarization between the tip, the sample, and the metallic objects. Taking also into account the cantilever and macroscopic shape of the tip, the theory gives us a quantitative value for the electrostatic interaction between the tip and the objects over the surface. Experimental data of frequency shifts in an oscillating tip induced by grounded and isolated nanotubes are analyzed finding an excellent quantitative agreement between experimental data and numerical calculations.
