Abstract

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.
