单壁碳纳米管阵列场效应特性的研究

单壁碳纳米管(Single-walled carbon nanotube,SWCNT)有许多异常的电特性,要完全实现其在实际电子系统中的潜在应用价值,需要在器件与电路的结合上有不断创新的方法。由于SWCNT在电子学上分为金属型和半导体型两大类,其中每一大类根据手性的不同在电特性上又各有差异,再加上要合成或合成后分离出单一手性的SWCNT,目前的技术还存在相当大的难度。结合化学气相沉积中的控制生长、控制转移排列整齐有序的SWC-NT阵列与微加工工艺等方法,将SWCNT阵列作为一个器件单元来进行测试,测试结果显示了一定的场效应特性。

Field-effect Investigation on Single-walled Carbon Nanotube Array

Single-walled carbon nanotubes(SWCNT) have many exceptional electronic properties.Realizing the full potential of SWCNT in realistic electronic systems requires a scalable approach to device and circuit integration.Because SWCNT can be classified as metallic and semiconducting in electronics;the two main sorts have different electrical characteristics depending on chirality;in addition,the difficulties of either selective synthesis or post-synthesis separation are seen as the primary roadblock in technologies.The methods of controlling growth in chemical vapour deposition,controlling transfer upon well-aligned SWCNT array,and micro fabrication art are combined to measure a field-effect device based on SWCNT array.The measured results show a certain degree of field-effect characteristics.
