Electro-thermal characterization of single-walled carbon nanotube (SWCNT) interconnect arrays

We investigate electro-thermal properties of metallic single-walled carbon nanotube (SWCNT) interconnect arrays biased by a signal voltage in this paper, where temperature distribution, breakdown voltage, and current carrying capability are captured by solving one-dimensional heat conduction equation of the SWCNT. Two electro-thermal equivalent circuit models of single SWCNT and a SWCNT array are proposed to illustrate hybrid effects of SWCNT length, biasing voltage, and temperature on their signal integrities. Simulation results indicate that self-heating effect should be considered carefully in the design of local SWCNT array interconnect as it is biased by a high signal voltage.
