Abstract(in English) | A new simultaneous measuring system for tunneling current and surface potential has been developed. An electrochemically etched tungsten tip is used as a probe electrode. The distance (d) between a sample and the tip is changed sinusoidally with high precision. The tunneling current flows periodically in accordance with the vibration of the tip when d becomes as small as a few nm. The surface potential is measured using the principle of the Kelvin method in which the displacement current due to the presence surface potential and change in capacitance difference between the tip and the sample is detected. Simultaneous measurement of the tunneling current and the displacement current has been attained by utilizing their phase difference of a vibration of the tip. The method for determining the tip peak radius and d is also presented. |
