利用电流感应加热技术，即焦耳加热技术，实现了导电纳米线的焊接。在系统中施加恒定直流电，使两根Pt纳米线的自由端接触，并成功焊接在一起形成连续的直纳米线。利用锥形探头向焊接纳米线提供大电流，可以在纳米线的某一点上切割焊接纳米线。还演示了搭接焊和异种金属焊接。(c) 2007材料学报Elsevier Ltd.出版。版权所有。
A technique to weld conducting nanowires has been realized by current-induced heating, i.e., Joule heating. A constant direct current was applied to the system, where the free ends of two Pt nanowires were contacted, and the ends were successfully welded together to form a continuous straight nanowire. Welded nanowire can be cut at a point on the wire by supplying a high-current to the wire with a cone-shaped probe. Lap welding and a dissimilar metal weld were also demonstrated.
