Assessment of the resonance frequency of cantilever carbon nanocones using molecular dynamics simulation

Abstract

The resonance frequencies of cantilever carbon nanocones (CNCs) up to 4 nm in height are determined using molecular dynamics simulation based on adaptive intermolecular reactive empirical bond order potential. The frequency content of the free vibrations of CNCs under a lateral initial excitation at the tip is analyzed using fast Fourier transformation, and the resonance frequencies are obtained. The results are reported for various samples to investigate the dependency of the resonance frequency to the geometrical parameters and temperature of CNCs.

“…It is noted that the first two order natural frequencies of the BNNCs decrease with the increasing of the cone height. This phenomenon is similar with that of the CNCs provided by Hu et al [13], and Firouz-Abadi et al [14]. The apex angle has also significant influence on the first-order natural frequencies of the BNNCs, and the increasing apex angle will increase the first-order natural frequencies, which is in agreement with the result obtained by Hu et al [13].…”

“…The single-layer cone-shaped nanostructures including carbon nanocones (CNCs) and BNNCs are considered as potential candidates for electron field emitters, resonators/mass detectors and highspeed AFM probe tips [11][12][13][14]. The BNNCs with different apex angles have been experimentally synthesised and observed using transmission electron microscopy and the electron diffraction technique [15][16][17].…”
