Abstract:
This paper introduces a new type of nano-oscillators constructed from a chloride ion inside an open carbon nanocone (CNC) decorated by functional groups at both small and wide ends. Using the 6-12 Lennard-Jones (LJ) and Coulomb potential functions, a continuum-based model is employed to analytically determine the van der Waals (vdW) force between ion and CNC and the electrostatic force between ion and functional groups. Using the Runge-Kutta numerical integration scheme, the equation of motion is also solved to arrive at the time histories of separation distance and velocity of ion. The effects of sign and magnitude of functional groups charge and initial conditions on the oscillatory behaviour of system are examined. It is shown that higher frequencies are obtained when the electric charges of functional group at the small end of nanocone are different with the chloride ion charge. It is further observed that oscillation frequency is maximum when the ion is initially located near the equilibrium location and has zero initial velocity.
