Experimental Verification of Overlimiting Current by Surface Conduction and Electro-Osmotic Flow in Microchannels
Direct evidence is provided for the transition from surface conduction (SC) to electro-osmotic flow (EOF) above a critical channel depth (d) of a nanofluidic device. The dependence of the overlimiting conductance (OLC) on d is consistent with theoretical predictions, scaling as d[superscript −1] for...
