A novel dual-signal output screwing oscillator built on carbon@MoS2 heterogeneous nanotubes (CNT@ MST) is proposed and its oscillation performance is investigated using the molecular dynamics method. The MST acting as a stator is the outer tube of the oscillator, while the CNT acting as a rotor is the inner tube to which an initial rotational excitation and an axial translational excitation are simultaneously applied. Compared with the traditional double-walled carbon nanotube (CNT@CNT) screwing oscillators, CNT@MST screwing oscillators have the following advantages: better stability, lower energy dissipation rates, and wider adjustable intertube spacing.
