Abstract
An analysis is given of the Kelvin method employing a variable shield potential, which takes nonuniformity of the surfaces into account. The influence of stray capacitance can be determined and eliminated by measuring as a function of spacing between the Kelvin electrodes for different values of the shield potential. These extended Kelvin measurements make it also possible to detect nonuniformity of the sample electrode and to eliminate its influence in certain cases, as is demonstrated by measurements on a vacuum cleaved TiO2 (rutile) (110) surface.
