Mercury film electrodes (mfe) have been prepared on several substrates and examined using scanning tunneling microscopy (STM). Surface waving was found to be at least one order of magnitude smaller in amplitude than that observed on bulk mercury drops. A solid/liquid/gaseous interface was observed, as was the amplitude of surface waves under various imaging conditions. No resonance condition was observed in these systems. A simple system for exciting surface waves was developed, and used to investigate surface waving of mercury during exposure to various conditions. The source of these waves remains unknown.
