Stepped horn actuated Kelvin probe
Review of Scientific Instruments, 2008 We have developed an original Kelvin probe system using an ultrasonic stepped horn sonotrode. This actuator is optimized in order to maximize the velocity of the tip end, and hence to increase the Kelvin current detected. Such development is essential to improve surface potential measurements at small spatial scale.

Quantitative Kelvin Probe Force Microscopy
MRS Proceedings, 2009 AbstractIn this paper we report on the investigation of electrostatic forces between a conductive probe and semiconducting materials by means of Kelvin probe force microscopy measurements. Due to the formation of an asymmetric electric dipole at the semiconductor surface, the measured KPFM bias is related with the energy difference between Fermi energy

Multitip scanning bio-Kelvin probe
Review of Scientific Instruments, 1999 We have developed a novel multitip scanning Kelvin probe which can measure changes in biological surface potential ΔVs to within 2 mV and, quasisimultaneously monitor displacement to <1 μm. The control and measurement subcomponents are PC based and incorporate a flexible user interface permitting software control of each individual tip ...

KELVIN PROBE’S STRAY CAPACITANCE AND NOISE SIMULATION [PDF]
Приборы и методы измерений, 2014 Stray capacitance effects and their influence on Kelvin probe’s performance are studied using mathematical and computer simulation. Presence of metal surface, even grounded, in vicinity of vibrating Kelvin probe produces the additional stray signal of complex harmonic character.
