Abstract
The abstract reports the fabrication, the enhanced field emission and the underlying physics of Au-Ag alloy nanoparticle capped silicon nanowires. It was found that the Au-Ag/Si nanojunction with space-charge-limited conduction in series with individual nanowire could improve the field emission stability and enhance the emission current by serving as a ballasted unit. This work clarifies the enhancement effect of a forward biased junction on field emission which is commonly ignored and provides a new method for obtaining high performance silicon nanowire field emitter.
