We developed a computational model for investigating the cause for the high ionic current through a single-walled carbon nanotube nanofluidic device by considering the electrical double layer at a solid-liquid interface. With this model, we were able to examine the influence of the Gouy-Chapman-Stern electrical double layer and the solution concentration on the ionic conductance in the device. ...
