For example, U.S. Patent No. 6,346, issued Feb. 12, 2002, to U.S. Patent No. 6,346, discloses a method for the direct growth of carbon nanotubes by chemical vapor deposition on the tip of an atomic force microscope. However, since this method cannot control the growth direction of the carbon nanotubes, there is still a problem of low efficiency and poor controllability, and the production cost is high. V. For example, the Chinese Patent No. 113 of the 99th ship, which was announced on September 25, 2002, discloses a method for recording single-walled carbon tubes. The first step of the financial method is to store the above-mentioned single-walled carbon nanotube water-soluble secrets for about one month; (2) to find the high-position position according to the different aqueous solutions, and to ride the required length of the carbon nanotube solution; (3) as required The amount of U coffee is diluted with deionized water i (4) to completely remove the oily impurities on the surface of the metal substrate; (5) the nano stone back tube is assembled on the substrate by the method of immersion or immersion. However, this method takes too long, is inefficient, and has poor controllability. - Therefore, it is necessary to provide a high-efficiency and controllable nanocarbon #assembly method and a nano-stone device.

The peak value of the alternating voltage is less than or equal to 10 volts. The assembly method may further comprise the step of separating the ends of the two conductors containing the carbon nanotubes to obtain at least one end of the conductor containing the carbon nanotubes. The assembly method can further include the steps of monitoring the assembly process to determine that the carbon nanotubes are assembled between the two.

低溶液14之濃度。反之，也可以通過調整溶液14之濃度，於-定程^^ 制被組裝之奈米碳管數量。 X 山溶液14可由吸管、移液管、注射器或其他適ϋ：之裝置移取並施加於末 =取與121之間。所施加之溶液14不宜過多，以使該兩辦1〇1與m 能共同浸入同一滴溶液14即可。另，也可將兩末端101與121 辱 置之由燒杯等容器盛放之溶液14中。 夕 步驟（2)中，所述之交流電壓之峰值最好於1〇伏以内，頻率於工千至 1〇兆赫茲之間。本實施例主要係依據雙向電泳法原理：於交流電場中，溶液 8 1260398 14中之奈米碳管於電場強度大之方向運動，最終運動到場強最大之兩尖端 101與121相對之區域，並被吸附到該兩末端1〇1與121上。此後，奈米碳 管依靠與該兩末端101與121之范德華力牢固吸附於末端1〇1與121之表面 上。一般，通電時間只需幾秒至幾十秒，因此該組裝方法耗時短，效率高。 請參閱第二圖，從光學顯微鏡照片可看出，奈米碳管被組裝到該兩末端 101與121之間’並且已被拉直。這係因爲奈米碳管於電場中被極化産生電 偶極距，兩端帶有電荷，電場對其作用力有一沿其軸向之分力，使奈米碳管 拉伸變直。The concentration of the low solution 14 is low. Conversely, it is also possible to adjust the concentration of the solution 14 to determine the number of assembled carbon nanotubes. X-X solution 14 can be removed by a pipette, pipette, syringe or other suitable device and applied between the end = take and 121. The applied solution 14 should not be too large, so that the two solutions 1 and 1 can be immersed in the same drop solution 14 together. Alternatively, the two ends 101 and 121 may be incinerated in a solution 14 in a container such as a beaker. In the step (2), the peak value of the alternating voltage is preferably within 1 volt, and the frequency is between 1000 and 1 megahertz. This embodiment is mainly based on the principle of two-dimensional electrophoresis: in an alternating electric field, the carbon nanotubes in solution 8 1260398 14 move in the direction of large electric field strength, and finally move to the area where the two ends 101 and 121 have the largest field strength, And is adsorbed to the two ends 1〇1 and 121. Thereafter, the carbon nanotubes are firmly adhered to the surfaces of the ends 1〇1 and 121 by virtue of the van der Waals force of the both ends 101 and 121. Generally, the power-on time is only a few seconds to several tens of seconds, so the assembly method is short in time and high in efficiency. Referring to the second figure, it can be seen from the optical micrograph that the carbon nanotubes are assembled between the ends 101 and 121 and have been straightened. This is because the carbon nanotubes are polarized in the electric field to generate the galvanic distance, and the two ends are charged. The electric field exerts a force along its axial direction to make the carbon nanotubes stretch and straighten.

The device includes ends 101 and 121 of two electrical conductors as electrodes, and a carbon nanotube connected axially between the two electrical conductors. The carbon nanotubes are attached to the surfaces of the two conductors, respectively, and are substantially straight along the axial direction thereof. It will be appreciated that the carbon nanotube device can be used in multiple applications, such as as a miniature sensor. When the carbon nanotubes are assembled, the solution 14 can be powered off and removed. It should be noted that the monitoring system can be used to monitor the entire assembly process for real-time monitoring, immediate adjustment, and improved yield. For example, according to the state in which the two ends of the unassembled carbon nanotubes are in an open state and the carbon nanotubes are assembled, the two are in a passage state, and the two states can be easily monitored. In the present embodiment, the monitoring method adopted is based on the principle of shame, and the circuit of the first-riding circuit (four) is connected to the resistor, and the waveform of the two ends of the resistor is detected by the waveform of the resistor. It means that the carbon nanotubes have been assembled to the two ends between 1〇1 and 121, and the electricity is removed and the droplets are removed. Of course, other monitoring methods and equipment may be used, and are not necessarily limited to the embodiment. Furthermore, the entire assembly process can be automated and monitored, avoiding the deviation of manual or semi-manual operation and the uncontrollability of carbon nanotube growth in chemical vapor deposition, improving production efficiency, and controlling t enhancement, At the same time, the required production equipment is drunk, the production cost is low, and it is suitable for mass production.
