Resonant Frequencies of Cantilevered (8,8)(3,3) Double-Walled Carbon Nanotube Resonator with Short Outer Wall
Abstract:Resonant frequencies of cantilevered (8,8)(3,3) double-walled carbon nanotube (DWCNT) resonators are investigated via classical molecular dynamics simulation. The interwall van der Walls forces as a nonlinear function had a great effect on noncoaxial vibration of DWCNT resonators. Bandwidths of DWCNT resonators with short outer walls were similar with each other irregardless to the structural difference. The frequency trends of DWCNT resonators with short outer wall were affected by the outer wall length. The vibration of the DWCNT resonator with short outer wall was very closely related to the vibration of the inner CNT in the stripped region.
