Abstract
In this paper we propose a quantitative model for the interaction between a sampling electrode and a sample surface in a Kelvin-probe surface potential measurement. We briefly describe the Kelvin method, then we introduce a capacitance based electrostatic model to quantify the interaction. We use this model to derive the Point Spread Function (PSF) of the measurement which can be used to enhance physical measurements using a deconvolution-based approach.
