<p>Apparatus for simultaneously effecting electro-chemical measurement and measurement of tunnelling current comprises circuitry (17) for setting a potential of a sample (11) and for detecting a current flowing between the sample and a counter electrode (13), circuitry (23) for changing the distance between the sample and the tunnel probe, and circuitry (20) for setting a potential of the tunnel probe and for detecting tunnelling current flowing due to the potential difference between the tunnel probe (3) and the sample (11). The tunnel probe is formed from a material selected from gold, a gold alloy containing gold as the main component, carbon, and a carbon compound.</p> |
