Carbon nanotube based resonant detector of modulated terahertz radiation

Abstract

A system of two freely suspended single walled carbon nanotubes in the form of a segment of a transmission line is considered. Its electrodynamic description is based on the Tomonaga-Luttinger liquid model. The system under investigation is a plasmon resonator with a resonance frequency from the terahertz range, which serves as a high Q mechanical oscillator coupled with the plasmon resonator by a nonlinear ponderomotive force. As a possible application of this system, a new model of resonant detector is proposed. The output parameters of such a nanosized detector are obtained.
