Analysis of Potential Barrier for Ionic Transport through Si3N4 Nanopores
Potential barrier plays a key role in ionic transport through nanoporous membranes. We numerically study the contribution of the potential barrier to the ionic current through a cylindrical Si3N4 nanopore using molecular dynamics simulations. We extract the height of the potential barrier from the b...

| description | Potential barrier plays a key role in ionic transport through nanoporous membranes. We numerically study the contribution of the potential barrier to the ionic current through a cylindrical Si3N4 nanopore using molecular dynamics simulations. We extract the height of the potential barrier from the best fit using a simple polynomial model of the ionic current. We reveal that the surface atoms make a contribution to the potential barrier. This study provides the height of the potential barrier so that it is valuable information about the underlying mechanism of ionic transport through nanopores. |
