Outline of Final Research Achievements

Electrochemical formation of silicon film has been studied in LiF-KF. The silicon nucleation process has been observed after conducting potentiostatic electrolysis at 0.7 V for 0.0002 seconds. The numbers of nucleation sites have increased with increasing the electrolysis durations. We confirmed that dendrites formation of silicon by prolonging the electrolysis times.
