Effect of electric fields on the surface of nanostructured electrodes on charge formation

The processing of the atomic force microscopy images of specific nanostructured electrodes made of different metals shows that the shape of a nanostructure’s peak can be well approximated using a parabolic dependence. The local electric fields and injection currents are calculated using the data on the nanostructured surface of electrodes with the aid of the Fowler–Nordheim dependence. A qualitative analysis is performed and the applicability of the proposed approach in the construction of the electroconvection mass- and heat-exchange devices is demonstrated.
