Transmission electron microscopy study of Si nanowires

Abstract
Microstructures of Si nanowires (SiNW’s) synthesized using laser ablation were investigated by transmission electron microscopy. The SiNW’s have a high density of structural defects, which may play an important role in the formation of SiNW’s and in the determination of the morphology of the nanowires. A model for the growth mechanism of the SiNW’s was discussed on the basis of the observation.
