Progresses of Nano Welding Technology Based on Nanojoining

基于纳米连接的纳米焊接技术是进行纳米制造的关键技术,各国科技工作者对此进行了不懈的探索。综述了基于纳米连接的纳米焊接技术的最新进展,包括基于热输入的熔化焊接和无热输入的冷焊接,介绍了通电热输入和以光作为热源的热输入以及纳米接触的自发焊接,焊接对象包括金、银等金属纳米线,以及碳纳米管等非金属纳米线。

The nanojoing or nanowelding technology is necessary to create the nano devices in nanofabrication. Many scientists of the world performed research toward joining nanowires to form nano function devices. Current nano welding technologies were introduced herein,including heat input of fusion welding and cold welding without heating. The direct current electric and light were used as heating source in fusion welding. The spontaneous welding of nanowire contact can be also finished without heat. The weldable materials were metallic nanowire such as gold, silver as well as non metallic carbon nano tubes（CNTs）.
