• boron-nitride nanotube oscillator
• molecular dynamics

The gigahertz oscillator behavior of double-walled boron-nitride nanotube (BNNT) was investigated by using classical molecular dynamics simulations. The BNNT oscillator was compared to carbon-nanotube (CNT) and hybrid-C@BN NT oscillators. BNNT and hybrid oscillators have higher frequencies than the CNT oscillators because the van der Waals forces of the BNNT and the hybrid oscillators are higher than the van der Waals force of the CNT oscillator: Since the frictional effects of BNNT oscillators are higher than that of a CNT oscillator, the damping factors of BNNT and hybrid oscillators are higher than that of a CNT oscillator.
