Since the discovery of carbon nanotubes, one-dimensional (1D) nanoscale materials have drawn much attention due to their peculiar and interesting physical properties and potential device applications. Recently, coaxial nanocable-like 1D structures comprising different kinds of materials have been successfully synthesized for a variety of purposes, such as making nanometer scale electronic devices with a variety of functions and protecting the 1D structures from contamination or oxidation, etc. Furthermore, as the demand for fabricating special nanowire structures increases, to develop the method not only for synthesizing a wide variety of nanowires but also for modifying or improving the properties of as-synthesized nanowires becomes very important. In the present study, we have fabricated the core-shell heteronanowires and investigated comparatively the core/shell structures before and after coating, with respect to their morphological, structural and Raman characteristics. In addition, the effects of thermal annealing on the Raman spectra have also been scrutinized.
