Abstract:
A method of using an electrolyte for fabricating a two-terminal nonlinear element comprising a first conductive film, an insulated film and a second conductive film, wherein said electrolyte comprises an organic solvent, water in a proportion of 1 to 10 wt % and a solute and has electrolytic conductivity being greater than or equal to 1 mS/cm but less than or equal to 100 mS/cm, said first conductive film is of tantalum or a tantalum alloy, and said insulated film has a relative permittivity of 10 to 25, comprising the step of:using said electrolyte to form said insulated film by anodic oxidation of said first conductive film, said anodic oxidation being at a current density of 0.01 to 0.1 mA/cm2.
