TRANSFER FUNCTION AND COMPACT DISTRIBUTED RLC MODELS OF CARBON NANOTUBE BUNDLE INTERCONNETS AND THEIR APPLICATIONS

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. 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. Further, a complete physical model for the transient response of carbon nanotube bundle interconnect is derived, which can also accurately predict the transient response of carbon nanotube bundle interconnect including time delay and crosstalk.
