Electrochemical Behavior of the Oxide Formed by Reduction of RuO4(2-): A ph-Dependent Ruthenium Oxide-Based Microelectrochemical Transistor

Abstract : Reduction of ruthenium tetraoxide ion in alkaline results in deposition of an oxide, RuO(x) exhibiting characteristics intermediate between redox conducting and electronically conducting materials. Like a conventional redox polymer, RuO(x) shows a well-defined cyclic voltammetry wave and a conductivity maximum at a potential close to the peak of the wave. Keywords: Ruthenium oxide, Microelectrochemical transistors.
