Figure 5: Diameter dependence of ion transport phenomena.
From: Diameter-dependent ion transport through the interior of isolated single-walled carbon nanotubes
(a) Pore-blocking current for each device separated by observed dwell time, with diameter and metallic/semiconductor nature marked. x Axis is displayed on a log scale (100–103 (ms)), all tested with 3 M KCl and 1 V applied voltage. (b,c) Observed pore-blocking current and dwell time as a function of SWNT diameter, along with the results from the electrochemical model. Error bars represent the range of measurements over the many stochastic events for each SWNT. (d) Illustration of the physical effects accounted for in the electrochemical model.
