| Resum: | The capacitance system of a hyperboloidal tip and a rough surface is usually encountered in
analyzing electrostatic force microscopy images. In this letter, a perturbation approach has been
applied to solve for the electric potential of this system, in which the rough surface is treated as
perturbation from a flat one. For the first-variation solution, the boundary value problem is
represented in the prolate-spheroidal coordinate system and solved in terms of a generalized Fourier
series involving conical functions. Based on this solution, the tip-surface Coulombic interaction can
be computed. Sample calculations have been applied to sinusoidal surface profiles |
