Outline of Final Research Achievements

The inverse-opal silicon films have been prepared by using ordered polystyrene (PS) templates in an electrochemical reduction of tetrabromosilane under various conditions. Self-assembled PS colloidal crystals with different diameters were used as templates. The electrochemical process was investigated by cyclic voltammetry. Scanning electron microscopy and absolute reflectance measurement confirm the morphology and optical property of the deposited silicon films. Moreover, the invere-opal nickel template as the working electrode was subjected to the electrodeposition of opal silicon films under the optimized conditions.
