Abstract

We positioned a single silver nanoparticle along the length of a carbon nanotube based resonator, and investigated the resonance frequency shift subject to the particle's position. We found that a curve derived from the classical continuum model can fit well to our experimental data, implying the applicability of the analytical formula even in the nanometer range. We also used the finite element simulation to elicit the subtle frequency difference caused by the radial angle of nanoparticle's position in reference to the vibrating plane of the resonator. This effect was found to have an insignificant correction to our measurement.
