Applications of Scanning Tunneling Microscopy to Electrochemistry
Abstract
Our research during the last contract period involved an evaluation of the efficacy of using partially insulated STM tips as ultramicroelectrodes in studies of heterogeneous electron transfer. We initially fabricated these electrodes to serve as tips for imaging surfaces in solutions that contain significant concentrations of electroactive species. The tips that we have prepared (by partially coating etched Pt wire with molten glass) can have diameters as small as a few nanometers, and, by the nature of their small size, are useful in examining fundamental quantities such as the heterogeneous electron transfer rate constant for redox species
