摘要：
Previous experimental results suggest that gas damping is a significant loss mechanism for carbon-nanotube-based mechanical resonators operating in low vacuum conditions. Using free-molecular flow theory for the gas and a continuum-based model for the nanotube resonator, a model for gas damping of single-wall carbon nanotube bridges and cantilevers is proposed. When compared to experimental data for a single-wall carbon nanotube bridge oscillator, the model agrees to within the limits of the known experimental geometry.
