Research Abstract |
A electrochemical cell was developed that utilized evaporated gold or platinum onto the organic thin films as working electrodes. X-ray fluorescence analysis of the electrode surface was realized by irradiating x-rays from the backside of the working electrode, and the potential of the working electrode was applied with the potentiostat controlled by the personal computer. The developed system was applied to the plating and stripping of copper thin film, and the concentration of bromide ion around the working electrode was detected with the x-ray fluorescence method.
