Oscillation of a CNT housed inside an interlayer-bridged CNS. (a) Snapshots of the axial oscillation of the bridged-CNS-based nano-oscillator at 25, 35, 45, 55, 65, and 75 ps, respectively. Note the oscillation of the CNS itself is fully constrained by the interlayer bridging bonds. (b) The evolution of CNT oscillation amplitude. (c) The peak amplitude of each oscillation cycle and the corresponding oscillation frequency as a function of time, respectively. The simulations are carried out at 100 K.
