Abstract
Silicon nanowires were prepared by laser ablation and hydrogen plasma treatment. The electron field emission phenomena were examined by measuring the current-voltage and current-electric field characteristics of the silicon-nanowire films at varying anode-sample separations and nanowire diameters, respectively. The work function, emission area, and field-enhancing factor were determined using the Fowler-Nordheim equation with the results of the current-voltage characteristics analysis.
