Mechanisms of 1D Crystal Growth in Chemical Vapor Deposition: ZnO Nanowires

Abstract:

Abstract. ZnO nanowires synthesis throught oxidative evaporation of pure zinc powder without catalyst is studied in detail to understand the nucleation and growth mechanisms involved with the so-called “self-catalysis” schemes. The structural features associated with different growth stages were monitored using scanning electron microscopy (SEM), describe the direct observation of the nucleation and growth process. X-ray diffraction (XRD) and energy-dispersive X-ray spectroscopy (EDS) demonstrate that the as-obtained sample can be indexed to high crystallinity with wurtzite structure and only contain Zn and O without the presence of any impurities.
