Electron field emission from silicon nanowires
TLDR
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.Abstract:
Silicon nanowires (SiNWs) were synthesized using laser ablation. 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. The field emission characteristics of the SiNW film were studied based on current–voltage measurements and the Fowler–Nordheim equation. The electron field emission increased with decreasing diameter of SiNWs. A hydrogen plasma treatment of the SiNW film aimed at reducing the oxide overlayer improved the emission uniformity of the film.read more

Nanowires: properties, applications and synthesis via porous anodic aluminium oxide template
TL;DR: The physical properties of nanowires are influenced by the morphology of the nanowire, diameter dependent band gap, carrier density of states etc. as mentioned in this paper, which is different from that of their parent counterpart.
