Description: 
We report the self-assembly of core–shell GeTe/Sb 2 Te 3 nanowires (NWs) on Si (100), and SiO 2/Si substrates by metalorganic chemical vapour deposition, coupled to the vapour–liquid–solid mechanism, catalyzed by Au nanoparticles. Scanning electron microscopy, X-ray diffraction, micro-Raman mapping, high-resolution transmission electron microscopy, and electron energy loss spectroscopy were employed to investigate the morphology, structure, and composition of the obtained core and core–shell NWs. A single crystalline GeTe core and a polycrystalline Sb 2 Te 3 shell formed the NWs, having core and core–shell diameters in the range of 50–130 nm and an average length up to 7 µm. View Full-Text
