摘要

We explore the frequency characteristics of triple-walled carbon nanotube (TWCNT) oscillators using molecular dynamics simulations. The fast Fourier transform results of the TWCNT oscillators show both primary (f(1)) and minor (f(2)) peaks. The frequency characteristics of TWCNT oscillators are closely related to the amplitude (A(1)) of the primary peak. Both f(1) and f(2) linearly increase as a function of A(1) for A(1)(-0.5) < 0.45, whereas f(1) and f(2) slightly decrease as a function of A(1) for A(1)(-0.5) > 0.45. f(1) for all TWCNT oscillators is always less than the frequency of the double-walled CNT oscillators, while f(2) is less than the operating frequencies of double-walled CNT oscillators for A(1)(-0.5) < 0.3. As a function of A(1)(-0.5), f(2) was almost two times higher than f(1).
