Figure 3.

J-E curves of SiNWs coated with different thicknesses of Au film and post-annealed at 650°C, which show that the 650°C post-annealing processing of Au/SiNWs makes J-E curves shifting to lower applied field and enhances FE properties of SiNWs. The similar results have been obtained in Au/SiNWs with different thicknesses. The inset shows corresponding F-N plots.
