Electrostatic capacitance extraction for carbon nanotube bundle interconnects

The electrostatic capacitance depending on interconnect geometry is very important for the performance analysis of carbon nanotube (CNT) bundle. In this paper, electrostatic capacitance of each individual CNT in the bundle will be extracted accurately by Ansoft Maxwell. The results show that the ratio of electrostatic capacitance and total capacitance in CNT bundle becomes larger with decreasing the number of CNTs, and the electrical performance is significantly related to the electrostatic capacitance.
