Abstract
By way of molecular dynamics simulation, a physically realistic nanochannel with consideration of the thermal motion of channel walls is proposed, and the distributions of water and ions in the electrical double layer region on a charged silicon surface are observed. It is found that the distribution profile of Na+ ions has double peaks corresponding to the Stern electrical double layer model. Also, the water distribution profile in the 3.0 nm nanochannel agrees very well with that observed in a previous experiment (Cheng et al. Phys. Rev. Lett. 2001; 87: 156103). In addition, the height of nanochannel has negligible effect on the thicknesses of the water layers, but affects the peak numbers of water density distributions dramatically.
