Nickel Salt Effect on Macroporous Silicon Immersed in Fluoride Solution: From Silicon Microtubes to Nickel Microtubes

摘要

The porous silicon is a suitable material for different applications in the different technological fields such as sensor devices (1,2) and photonic devices (1-3), Its versatility for many photonic device fabrications is due to its interesting physical and chemical properties which could be tunned just by controlling the electrochemical parameters in the anodization process used for porous silicon formation (1,3). On the other hand, the micro and nano-metallic structure has achieved the great interest in the scientific community because this one showed to have a broad new possible applications like as nanocomposites system (4,5), and photonic crystal devices (6). For this reason, several researchers have devoted many efforts for the development of new techniques and process in order to fabricate metallic micro and nano structures and one of these methods used the template substrate for molding the metallic nano structure features (4-11).
