Analysis of Geometrical Aspects of a Kelvin Probe
Publié en 2016
The presented analysis investigates the capacitance characteristic of a Kelvin probe regarding the geometrical transition from a movable electrode plate to a narrow tip. Moreover, predictions can be done concerning optimum geometry, sensitivity and suitable electrical measurement circuitry. A further aim of this study is to provide optimal tip geometries for different sized Kelvin probes. This includes pitching the probes impedance and maximizing the current yield out of the contact potential difference between two metals.
