Reversal current observed in micro- and submicro-channel flow under non-continuous DC electric field |
(color online) Typical models of current signal curves at the initial stage. The current signals in panels (d), (e), and (f) are the reversal response of panels (a), (b), and (c), respectively. [(a) and (b)]: A typical exponential decay of I, where 0.05-M KCl, external voltage is 100 mV, 20 mV, respectively, pH = 7, the channel diameter is |
