Triple-walled carbon nanotube oscillator as high frequency device

Abstract

The coupled oscillation of triple-walled carbon nanotube (CNT) oscillators consisting of (5n,5n) CNTs was investigated by using molecular dynamics simulations. High frequencies of triple-walled CNT oscillators are higher than frequencies of double-walled CNT oscillators. In spire of the different core CNT, the frequency peaks due to the interwall coupling are similar to each other as the number of walls increases. The operating frequencies due to the coupled motions for triple-walled CNTs can be estimated by the classical differential equations.
