MoS2 nanotubes, carbon nanotubes, oscillators, hetero-nanotubes, molecular dynamics
Oscillatory behavior of novel heterogeneous oscillators composed of carbon andmolybdenum disulfide nanotubes (CNT@MST) was investigated for the firsttime, by using the methods of classical molecular dynamics. In the proposedoscillators, a molybdenum disulfide nanotube (MST) was set as an outer tube,leading to better compatibility with the semiconductor industry standards. Asmooth and stable oscillator with a frequency reaching 20 GHz was obtainedbased on a double-walled CNT@MST hetero-nanotube for a wide range of gapwidths, indicating that the proposed oscillators perform much better than thosebuilt from double-walled carbon nanotubes (CNTs) that require a narrow range ofgap widths. In addition, the oscillation characteristics of CNT@MST oscillatorscontaining different inner and outer tube chirality were significantly better thanthose of CNT@MST oscillators containing two tubes with the same chirality.
