摘　　要：用C+离子束轰击多壁碳纳米管后, 发现了大量的由无定形碳纳米线组成的连接结构. 这种用高分辨透射电子显微镜和电子衍射分析确认的离子束焊接方法, 不但可以作为准备纳米电子(光子)学器件和线路的手段, 结合微操纵技术, 也有可能对其它系统器件排布的制作有所贡献.We have demonstrated for the first time that a larger amount of junctions were formed by multi-wall carbon nanotubes (MWCNTs)-converted amorphous carbon nanowires (ACNWs) during carbon ion beam irradiation. This is very suitable for production of novel type junction-like structiures consisting of (amorphous) nanowires with uniform diameter of trunk and branches. The present method, ion-beam weld (IBW) of crossed MWCNTs, not only used to provide a powerful way in which to achieve perfect welding to build various junction-like structures, but also may be helpful for preparing other systems or aligned arrays on substrates by micro-manipulator for potential device.
