摘要

奈米螺旋碳管因具有特殊的三維立體結構，故近年開始廣泛被討論及研究。
本研究希望利用建立一簡易量測流程來測量碳管的電性。首先使用介電泳的方式來快速的組裝元件，使碳管跨接於兩電極之間，再用光學顯微鏡觀測附著的情況，再來量測直流特性及高低頻下之電性，最後藉由電子顯微鏡來觀測螺旋碳管的基本型體構造。
實驗中所用來組裝的電壓約為0.8~1.2V/um，操作頻率為1~10KHz，跨接的碳管其長度約5~12um之間，測量的電阻率約1~13X10-3Ωm，高頻下其目前量到的特性為電容性。
本研究希望藉此為碳管之後發展微電路上做一初步的探討，並相信未來螺旋碳管能有好表現。

The carbon nano-coil has special three-dimensional structure, so it begins to be discussed and studied extensively in recent years.
This research hopes to set up a simple and easy procedure to measure the electrical properties of carbons. First, fast assembles component by using dielectrophoresis to make the coil connection of two electrodes, and observing the situation of adherence by using optical microscope, and examines the electrical properties under DC characteristic and high low frequency, finally, using the scanning electron microscope to observe the basic structure of carbon nano-coil.
The voltage usage and assembly in the experiment is about 0.8~1.2V/um, and operate frequency is 10KHz, and the length is about 5~12um between carbon connection, resistance is about 1~13X10-3Ωm, the characteristic is capacity under the high frequency.
This study hopes to make the preliminary discussion on micro- electronics circuit for carbon nano-coil, and believing there is a good development in the future.
