Journal ArticleDOI
Silicon nanowires prepared by laser ablation at high temperature
TL;DR: The lattice structure and constant of the nanowires as determined from x-ray diffraction (XRD) are nearly identical to those of bulk Si, although the relative XRD peak intensities are different from those of randomly oriented Si crystallites.
Journal ArticleDOI
Nucleation and growth of Si nanowires from silicon oxide
TL;DR: In this paper, a growth mechanism was proposed based on the microstructure and different morphologies of the Si nanowires observed by means of transmission electron microscopy (TEM).
Journal ArticleDOI
Si nanowires grown from silicon oxide
TL;DR: In this paper, a bulk-quantity Si nanowires have been synthesized by thermal evaporation of a powder mixture of silicon and SiO2, and it was shown that at the initial nucleation stage, silicon monoxide vapor was generated from the powder mixture and condensed on the substrate.
Journal ArticleDOI
SiO2-enhanced synthesis of Si nanowires by laser ablation
TL;DR: In this article, the morphology and microstructure of the Si nanowire tips have been systematically characterized by means of high-resolution transmission electron microscopy, and the results suggest that Si oxide is more important than metal in catalyzing the formation of Si nano-connections.
Journal ArticleDOI
Electron field emission from silicon nanowires
TL;DR: In this article, a continuous SiNW film was prepared by grinding the pieces of sponge-like SiNWs to powder, then dispersing and sticking the powder onto a Si wafer.
