Multi-Walled Carbon Nanotube Oscillators as Multi-Frequency Generators for Nano Embedded Systems
The coupled oscillation of multi-walled carbon-nanotube (MWCNT) oscillators consisting of (5n,5n) CNTs was investigated by molecular dynamics simulations. The results show that the inter-wall coupling leads to frequency splits, and there are consistently three primary frequency peaks for the quadric-walled, penta-walled and hexa-walled CNT oscillators, independent of the wall diameters, suggesting applications as triple-frequency generators. Furthermore, at least one of the primary frequencies of a MWCNT oscillator is lower than that of its double-walled counterpart.
