Control of SWCNT-interconnect performance by tube-diameter

An analysis of the influence of tube diameter on single-walled nanotube (SWCNT) bundle interconnect delay is presented. The analysis shows that due to low resistance and inductance SWCNT-bundle interconnect is of lower delay than copper interconnect. Delay increases with increase in tube diameter of SWCNT. It is desirable to restrict tube diameter to the minimum possible.
