Abstract
A first modulation voltage is applied to a thin film. An amount of a change in the phase of a current carried through the thin film with respect to the phase of the first modulation voltage is compared with a threshold. Upon detecting that the amount of the change in the phase exceeds the threshold is detected, the application of the first modulation voltage is stopped. Thus, a nanopore is formed on the thin film at high speed.
