Abstract :
We propose the use of coiled carbon nanotubes (CCNTs) as nanoscale electrical inductor elements, inspired by the paradigm of function follows form. We show through computations that a range of inductance values (in the pH to μH) operational at terahertz frequencies could be obtained through a variation of CCNT geometric parameters, which can be accomplished through rational synthesis. A comparison of the proposed inductor material to conventional inductor material e.g., copper, in terms of both component footprint and material volume, indicate a greater quality factor (Q=ωL/R) through the use of the CCNTs.
