Figure 1From: Fabrication of Coaxial Si1−x Ge x Heterostructure Nanowires by O2 Flow-Induced Bifurcate ReactionsSchematic of the Si1−x Ge x heterostructure nanowires synthesized procedure. After the growth of Si1−x Ge x nanowires, the flow of SiCl4 was terminated and then a flow of O2 was introduced under vacuum maintained by mechanical pumpBack to article page
