Electrochemical Model for Field Effect Conductivities of Electrolytes in Equilibrium Systems
Field effect electronic and ionic conductivities come from the electronic and ionic resonances and polarizations in an electrolyte. An external atmosphere field causes field enhanced electronic conductivity and field depressed ionic conductivity. The higher molar formation Gibbs energy of the pi side than that of the ni side in a pin electrolyte heterostructure results in field enhanced electronic conductivity and field depressed ionic conductivity on the pi side as well as field depressed electronic conductivity and field enhanced ionic conductivity on the ni side. An impedance spectrum arises from polarizations at high temperature but from both polarizations and resonances at low temperature. The electrochemical model demonstrates the origins of field effect conductivities in an electrolyte under equilibrium.
