Microarrays of ring-recessed disk electrodes in transient generator-collector mode: theory and experiment.
The fabrication, characterization, and use of arrays of ring-recessed disk microelectrodes are reported. These devices are operated in generator-collector mode with a disk acting as the generator and the ring as the collector. We report experiments and simulations relating to time-of-flight experiments in which material electrogenerated at a disk is diffusionally transported to the ring. Analys...
متن کاملPolysilicon Interdigitated Electrodes as Impedimetric Sensors
The suitability of polysilicon as a material for the fabrication of interdigitated electrodes and their application to the development of sensors is studied in this work. The main interest in using this material lies in the possibility of obtaining integrated sensors with commercial CMOS technologies and simple post-processing steps. Electrodes with 3μm finger width and 3, 10, and 20μm spacing ...
متن کاملRing dark solitary waves: experiment versus theory.
Experimental results on optical ring dark solitary wave dynamics are presented, emphasizing the interplay between initial dark beam contrast, total phase shift, background-beam intensity, and saturation of the nonlinearity. The results are found to confirm qualitatively the existing analytical theory and are in agreement with the numerical simulations carried out.
متن کاملScanning electrochemical microscopy. 41. Theory and characterization of ring electrodes.
Ring ultramicroelectrodes, which are of particular interest as probes for scanning electrochemical microscopy (SECM), combined with near-field scanning optical microscopy, were investigated. Theoretical SECM tip current-distance (approach) curves for a ring electrode were calculated by numerical (finite element) analysis. The SECM curves obtained were a function of the geometry of the tips incl...
متن کاملInterdigitated coplanar electrodes for enhanced sensitivity in a photorefractive polymer.
Organic photorefractive polymer composites can be made to exhibit near 100% diffraction efficiency and fast writing times, though large external slants are needed to project the applied field onto the grating vector. We show here that the use of interdigitated electrodes on a single plane provides similar performance to these standard devices and geometries but without a external slant angle. T...
