ABSTRACT:
In a system for measuring a surface potential of a sample, a probe is located above. A surface of the sample with a small gap and is vibrated by a piezoelectronic element which is energized by a oscillator. A potential of the distal end of the probe is changed and is converted into an electrical signal. The surface potential is obtained from the electrical signal.
