在设备基于单个墙的碳 nanotube (SWCNT ) 穿的 nanoelectronic 的制造过程, SWCNT 和在数组的金属性的 SWCNT 的性质修正的面向的排列是要解决的关键问题。有底层的脉搏气体排列向下倾斜被建议认识到 SWCNT 的可控制的排列。试验性的结果证明 84% SWCNT 在 −15 ° − 被排列;对脉搏气体方向尖的 15 °。一种修改 nanomanipulation 技术基于原子力量显微镜( AFM )被利用执行 SWCNT 操作的各种各样的类型,例如从“ Y ”的 SWCNT 分离 CNT ,从 SWCNT 结束的催化剂移动, SWCNT 上的不断的 nano 扣环制造并且碎的平拉长,它提供一个可行方法修改尺寸,形状和 SWCNT 的电的性质。
In the fabrication process of nanoelectronic device arrays based on single-wall carbon nanotube (SWCNT), oriented alignment of SWCNTs and property modification of metallic SWCNTs in the array are the key problems to be solved. Pulse gas alignment with substrate downward tilt is proposed to realize the controllable alignment of SWCNTs. Experimental results demonstrate that 84% SWCNTs are aligned in -15°- 15° angular to the pulse gas direction. A modified nanomanipulation technology based on atomic force microscope (AFM) is utilized to perform various kinds of SWCNT manipulation, such as SWCNT separation from the "Y" CNT, catalyst removal from the SWCNT end, continual nano buckles fabrication on SWCNT and even stretching to break, which provides a feasible way to modify the size, shape and the electrical property of SWCNTs.
