Abstract
A cell to permit in situ imaging of the electrodeposition of silver on gold <100> from a polymer electrolyte by TEM is described. The extremely thin electrochemical cells were composed of a layer of polyethylene oxide containing a silver salt between evaporated silver and gold electrodes. Cyclic voltammetry experiments in larger cells show the deposition and stripping behavior of silver on polycrystalline gold from the polymer electrolyte as a function of temperature. Observations in preliminary in situ TEM experiments include the nucleation and growth, and coalescence of silver islands oriented epitaxially to the gold electrode.
