A substrate-supported carbon nanoscroll (CNS) oscillator is demonstrated through molecular dynamics simulations. By tuning the effective surface energy of CNS to a certain range (e.g., via an applied electric field), a substrate-supported CNS whose core is constrained by an inserted carbon nanotube can be made to oscillate around an equilibrium configuration at frequencies on the order of 10 GHz. It is found that stiffer core insertions lead to smaller damping coefficient and higher oscillating frequency, while temperature has a pronounced influence on the oscillating amplitude.
