Abstract:The vibrational characteristics of a cantilevered double-walled carbon nanotube (DWCNT) resonator are studied using molecular dynamics (MD) simulations. The effects of temperature, nanotube type, ratio of tube length to diameter, and ratio of tube length between inner and outer walls on the resonant frequency of DWCNT with a long outer wall are evaluated. The simulated results show that DWCNTs have a very high frequency range from 10 to 250 GHz, which strongly depends on nanotube type and geometry characterist… Show more
