【摘要】：随着科技的发展,金属纳米线在纳米器件中的应用越来越多,比较典型的如纳米路由器、等离子体波导等。近些年来,随着透明电极在导电薄膜中的应用越来越广泛,基于金属纳米线网络的透明电极的研究也越来越多。在很多以纳米线为元件的器件中,将金属纳米线连接起来在某些方面可为器件带来更好的特性,例如,金属纳米线做成的透明电极,如果纳米线之间焊接在一起,那么整个网络的导电性能将得到大幅提升。本文提出一种基于光热效应的焊料牺牲式激光焊接技术,其最大的优势在于保留了原始结构在焊点的完整性,这是其他焊接方法所不能做到的。本文首先回顾了金属纳米线的一些合成方法以及在纳米光子学当中的应用。第二章从两个角度,即纳米线网络大规模焊接、局域纳米线点焊接,这两个方面回顾了目前已经得到应用的纳米线连接方法,并着重讲述了钎焊技术,因为本文所提出的焊接方法也属于这一范畴。第三章,首先研究单根银纳米线的熔断特性,基于此提出本文所述的焊接方法,不同结构的两根纳米线可用此方法焊接起来,同时我们对焊接前后的电学特性进行了测量。第四章,将这种技术应用到不同材料和不同结构之间的焊接当中,证明了这种技术在纳米焊接领域的多用性。第五章是对整篇文章的总结,同时对这种技术在未来的发展和应用提出了一些展望。
[Abstract]:With the development of science and technology, more and more applications of metal nanowires in nano devices, such as nano router, plasma waveguide. In recent years, with the increasing application of transparent electrodes in conductive film more extensively in the study of transparent electrode metal nanowire networks are more and more. Based on many components of the device the nanowires, such as properties, nano metal wire together in some ways can bring a better device, a transparent electrode made of metal nanowires, if the nano wires are welded together, then the conductive performance of the whole network will be greatly improved. This paper presents a photothermal effect based on laser solder sacrifice the welding technology, its biggest advantage is to retain the original structure in the integrity of solder joints, which is the other welding methods cannot be done. This paper first reviews the metal nano Some synthetic methods and applications in the line of nano photonics. In the second chapter, from two angles, namely the nanowire network local welding, spot welding nanowires, these two aspects are reviewed at present has been applied to nano wire connection method, and emphatically describes the brazing technology for welding method proposed in this paper is belong to this category. In the third chapter, firstly, the fuse characteristic study of single silver nanowires, the welding method mentioned in this paper are put forward based on this, two welding nanowires with different structures can be used in this way, we on the electrical properties before and after welding are measured. In the fourth chapter, the application of this technology to welding between different materials and different structures, proved that the field in nano welding this technology. The fifth chapter is the summary of the whole article, and the development and application of this technology in the future Some prospects are put forward.
