Abstract
We report on the self-assembly of core-shell Ge/In-Te nanowires (NWs) on single crystal Si substrates by Metalorganic Chemical Vapour Deposition (MOCVD), coupled to the Vapour-Liquid-Solid (VLS) mechanism, catalysed by Au nanoparticles (NPs). The NWs are formed by a crystalline Ge core and an InTe (II) shell, have diameters down to 15 nm and show <110> oriented growth direction. The role of the MOCVD process parameters and of the NPs size in determining the NWs core-shell microstructure and their alignment was investigated by high-resolution TEM, EDX, XRD and Raman spectroscopy.
