1 Raman analysis of oxide cladded Silicon core nanowires grown with solid silicon feed stock

One-dimensional nanostructures have attracted much attention due to their novel properties and potential applications in nanoelectronics and nanophotonics (Tian et al. 2007; Byun et al. 2009; Chan et al. 2008). Over the past decade, silicon nanowires have been synthesized and studied for their nanoscale properties Li et al. 2005; Kim et al. 2009). Structures of nanoscale dimensions show enhancement of properties, most often independent of th
