A hollow-core photonic crystal fiber (PCF) made of silicon is reported for the first time. The fiber is obtained by converting silica fiber to porous silicon using magnesiothermic reduction.
SiC nanocrystals growth through the surface reaction between spin-on C60 dissolved in Carbon Disulphide (CS2) and Si substrate and 800degC (100 rains.) annealed has been investigated. Scanning Electron and Atomic Force Microscopy showed the crests of C60 clusters formed preferentially on the Si substrate steps with 40-60 nm cluster sizes. Silicon carbide nanocrystallite formation after anneal. has...
