Signal transmission analysis of carbon nanotube bundle interconnects

According to the derived transfer function using different orders of approximation, stability and signal transmission analysis of a driven metallic single-walled carbon nanotube (SWCNT) bundle interconnect are performed in the present study. It is shown that as the length of SWCNT bundle interconnect increases, the poles will be closer to the imaginary axis, which causes the transmitted signal response tends to be more damping. Using the fourth-order approximation of the transfer function, the transmitted pulse waveform along the SWCNT bundle interconnect is captured accurately, with signal overshoot and time delay examined in detail.
