Introducing Field Effect Electroosmosis and Three and Two Dimensional Plots of Zeta Potential for Ideal Case of Metal-Insulator-Electrolyte Structure

摘要

The characteristics of the metal-insulator-electrolyte interface (MIE), under quasi equilibrium conditions, have been studied theoretically. Mathematical model of the MIE has been developed for ideal case. In the ideal case, a totally blocked interface has been assumed, such that the MIE behaviour is governed only by electrostatic factors. By combining MIE characteristics and the electroosmosis effect in a capillary, a novel effect called filed effect electroosmosis can be postulated. Based on this effect, a new device called a metal-insulator- electrolyte-electrokinetic field effect device (MIEEKFED) can be designed. Two and three dimentional plots for zeta potential as a function of V_G, the potential between metal and electrolyte and the concentration of electrolyte are presented.
