摘要

摘要报道了金-银合金纳米颗粒包覆硅纳米线的制备、场发射增强和基本物理特性。研究发现,将具有空间电荷限制导通的Au-Ag/Si纳米结与单根纳米线串联在一起,作为一个有碴单元,可以提高场发射的稳定性和增强发射电流。阐明了正向偏置结对场发射的增强作用,为获得高性能硅纳米线场发射体提供了一种新的方法。

Space-Charge-Limited Conduction in Forward Biased Schottky Junction and Its Effect on Field Emission from Crystalline Gold-Silver Alloy Nanoparticle Decorated Si Nanowire
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.
