Electrical modeling of multi-walled carbon nanotube (MWCNT)-based capacitors for high-density RF integration

Abstract

Modeling of multi-walled carbon nanotube (MWCNT)-based capacitors is performed in this paper. Their equivalent circuit model is modified with the impacts of quantum capacitance as well as kinetic inductance treated in an appropriate manner. Further, both effective capacitance and quality factor of the MWCNT-based capacitors are predicted even at ultrahigh frequencies, and their self-resonance frequencies are also captured successfully.
