Using molecular dynamics simulations, the oscillatory behavior of carbon nanotube oscillators containing sp3-hybridized defects formed by hydrogen chemisorption were investigated. It was found that the presence of these defects significantly affected the kinetic and potential energies of the nanotube systems, which in turn affected their oscillation periods and frequencies. Also studied were the oscillatory characteristics of the oscillators containing sp3-hybridized Stone-Wales defects. The results showed that it was possible to control the motion of the inner nanotube by introducing sp3-hybridized defects into the outer nanotube, which provided a potential way to tune the oscillatory behavior of nanotube oscillators.
