Two different CdS nanowires were synthesized, whose axial directions are in parallel with [00011 or [0 (1) over bar 10]. The [0001]-nanowires sustained one-dimensional growth characteristics irrespective of reaction temperature and duration. On the other hand, we observed two-dimensional lateral growth in the [0 (1) over bar 10]-nanowires. We proposed a three-step process for the morphological evolution of CdS nanowires to nanosheets; (1) nucleation and growth of nanowires by vapor-liquid-solid mechanism, (2) side-branching of secondary nanowires perpendicular to the original nanowires and filling between them by vapor-solid mechanism, and finally (3) formation of nanosheets through the repetition of side-branching and filling processes.
