用原子力显微镜操纵碳纳米管的研究
摘要:
使用原子力显微镜,在接触模式下实现了对单壁碳纳米管束的各种可控操纵,包括弯折、切割和劈裂等.发现操纵结果与针尖作用力以及碳纳米管束在基底表面的受力状况有关.当碳纳米管在一定程度上被固定在表面上时,能够可控地完成各种操纵；当针尖作用力足够大时,碳管束能够被针尖劈裂.这种操纵技术将有助于碳纳米管特性的测试和纳米电子器件的构筑.

Study on the Manipulation of Carbon Nanotubes with Atomic Force Microscopy
Abstract:
The technique of nanometer scale manipulation is very important in constructing nano-structures and nano-devices.By using atomic force microscope in contact mode, we have accomplished many kinds of controllable manipulations on single wall carbon nanotubes, including bending, cutting and splitting of nanotube bundles, etc. The results of the manipulation depend on the interaction between tip and nanotubes as well as between substrate and nanotubes. When nanotubes are fixed to some extent on the substrate surface, it will be easier to accomplish manipulations; when the force from the tip is stronger, bundles of nanotube can be splitted.
