A template-free and catalyst-free method for the growth of well-aligned nc-Si/SiOx composite nanowires was demonstrated. The structural and compositional characterization of the nanowires was studied by transmission electron microscopy (TEM) and electron energy-loss spectroscopy (EELS). It was revealed that the dendritic self-assemblies of Si nanorods were embedded in amorphous SiOx nanowires. The PL analysis showed that the nc-Si/SOx composite nanowires emitted blue-green light at room temperature.
