Characterization of a solid-state microelectrochemical diode employing a poly(vinyl alcohol)/phosphoric acid solid-state electrolyte: Rectification at junctions between WO3 and polyaniline
Abstract
The functionalization of an array of eight, closely-spaced (1.2 microns) Pt or Au microelectrodes each 50 microns long, 2 microns wide, and 0.1 microns thick with redox active WO3 and polyaniline and the electrochemical characterization of the WO3/polyaniline junction is reported. Chips consisting of microfabricated WO3 covering three of the available eight microelectrodes have been analyzed by Auger electron spectroscopy. The remaining five microelectrodes are available for further derivatization with polyaniline or can function as counterelectrodes.
