Characterizing the vibration behavior of double walled carbon nano cones for sensing applications

Abstract

This manuscript deals with the investigation of double walled carbon nanocones for resonance based applications. Dynamic analysis of Double Walled Carbon Nanocones (DWCNCs) with cantilever boundary condition and different disclination angles of 60°, 120°, 180°, 240° and 300° has been done through atomistic molecular structure modeling. This analysis is performed to evaluate and identify the variation in stiffness’s exhibited by these nano devices when used for sensing applications. Pristine and Defective double walled nano cones have been analysed to study the effect of defect on the stiffness variation when used as sensing devices. Results suggest a considerable effect of disclination angle of nanocone on the exhibited frequency response. The results can be attributed to the fact that with the change in the disclination angle and defects there is a substantial amount of variation in the stiffness due to the change in the bond orientation of the nanocones.
