Surface Electrons: Theory and Electrohydrodynamic Applications

The paper presents the theory of surface electronic states induced by a high-voltage field and considers applications of the theory of surface electrons to electrohydrodynamic flows. Theoretical considerations were carried out within the framework of a one-electron quantum mechanical model. It is shown that surface electrons initiate the injection of negative charg-es from the cathode into a liquid dielectric containing an electron-withdrawing impurity, for example, molecular iodine. Comparison of the theoretic and experimental data is satisfacto-ry
