Electrodeposition of Silicon in Organic Solvent Containing Silicon Chloride
In this paper it was investigated that silicon be electrodeposited in the room temperature from propylene carbonate solvent. Cyclic voltammograms indicated that it was possible to electrochemical reduction of silicon chloride at -2.3984V versuHg/Hg2Cl2/ KCl (saturation) quasi-reference electrode. Potentiostatic electrolysis yielded deposits, accompanied by the change in electrolyte color from transparent to brown. Scanning electron microscopy (SEM) and energy dispersion spectroscopy (EDS) were used to characterize the physical properties of the silicon. The EDS analysis performed simultaneously with SEM observation demonstrates that the deposit consists of Si, O and Cl.
