Nanowire morphology is known to depend in vapor-liquid-solid (VLS) technique on catalyst shape and size. We have investigated nanowire growing by VLS technique using pulsed laser deposition (PLD) approach. Nanostructures morphology has been studied from the laser ablation plume point of view. For the case of ZnO nanowires, plume control proved to have a crucial influence in controlling nanostructures morphology and outside an optimal range, the 'wire hape' is completely destroyed. A comparison between ZnO nanowire morphology obtained at different laser power is presented. Results for 'eclipse' deposition setup with some special masks are also included, together with the interpretation of some morphology results.
