Abstract :
A new tunable resonator is proposed with an electrostatically biased multi-walled carbon nanotube (MWCNT). The biasing voltage will induce the self-heating effect in the structure and lead to a nonuniform electric field distribution. The equivalent circuit parameters are obtained by numerically analyzing the related electrothermal coupling. Then, the resonant frequency of the resonator is calculated by the method of multiconductor transmission line. Applied with a proper biasing voltage of 0.6 V, the MWCNT-based resonator can provide a tuning range of 60% for the dominant resonant frequency.
